I should explain why I got so bothered by Ruth saying what she did. Those early months at the Cottages had been a strange time in our friendship. We were quarrelling over all kinds of little things, but at the same time we were confiding in each other more than ever. In particular, we used to have these talks, the two of us, usually up in my room at the top of the Black Barn just before going to bed. You could say they were a sort of hangover from those talks in our dorm after lights out. Anyway, the thing was, however much we might have fallen out during the day, come bed-time, Ruth and I would still find ourselves sitting side by side on my mattress, sipping our hot drinks, exchanging our deepest feelings about our new life like nothing had ever come between us. And what made these heart-to-hearts possible--you might even say what made the whole friendship possible during that time--was this understanding we had that anything we told each other during these moments would be treated with careful respect: that we'd honour confidences, and that no matter how much we rowed, we wouldn't use against each other anything we'd talked about during those sessions. Okay, this had never been spelt out exactly, but it was definitely, as I say, an understanding, and until the afternoon of the Daniel Deronda business, neither of us had come anywhere near breaching it. That was why, when Ruth said what she did about my not being slow making friends with certain veterans, I wasn't just cross. To me, it was a betrayal. Because there wasn't any doubt what she'd meant by it; she was referring to something I'd confided in her one night about me and sex.

As you'd expect, sex was different at the Cottages from how it had been at Hailsham. It was a lot more straightforward--more "grown up." You didn't go around gossiping and giggling about who'd been doing it with whom. If you knew two students had had sex, you didn't immediately start speculating about whether they'd become a proper couple. And if a new couple did emerge one day, you didn't go around talking about it like it was a big event. You just accepted it quietly, and from then on, when you referred to one, you also referred to the other, as in "Chrissie and Rodney" or "Ruth and Tommy." When someone wanted sex with you, that too was much more straightforward. A boy would come up and ask if you wanted to spend the night in his room "for a change," something like that, it was no big deal. Sometimes it was because he was interested in becoming a couple with you; other times it was just for a one-nighter.

The atmosphere, like I say, was much more grown up. But when I look back, the sex at the Cottages seems a bit functional. Maybe it was precisely because all the gossip and secrecy had gone. Or maybe it was because of the cold.

When I remember sex at the Cottages, I think about doing it in freezing rooms in the pitch dark, usually under a ton of blankets. And the blankets often weren't even blankets, but a really odd assortment--old curtains, even bits of carpet. Sometimes it got so cold you just had to pile anything you could over you, and if you were having sex at the bottom of it, it felt like a mountain of bedding was pounding at you, so that half the time you weren't sure if you were doing it with the boy or all that stuff.

Anyway, the point is, I'd had a few one-nighters shortly after getting to the Cottages. I hadn't planned it that way. My plan had been to take my time, maybe become part of a couple with someone I chose carefully. I'd never been in a couple before, and especially after watching Ruth and Tommy for a while, I was quite curious to give it a try for myself. As I say, that had been my plan, and when the one-nighters kept happening, it unsettled me a bit. That was why I'd decided to confide in Ruth that night.

It was in many ways a typical evening session for us. We'd brought up our mugs of tea, and we were sitting in my room, side by side on the mattress, our heads slightly stooped because of the rafters. We talked about the different boys at the Cottages, and whether any of them might be right for me. And Ruth had been at her best: encouraging, funny, tactful, wise. That's why I decided to tell her about the one-nighters. I told her how they'd happened without my really wanting them to; and how, even though we couldn't have babies from doing it, the sex had done funny things to my feelings, just as Miss Emily had warned. Then I said to her: "Ruth, I wanted to ask you. Do you ever get so you just really have to do it? With anybody almost?"

Ruth shrugged, then said: "I'm in a couple. So if I want to do it, I just do it with Tommy."

"I suppose so. Maybe it's just me anyway. There might be something not quite right with me, down there. Because sometimes I just really, really need to do it."

"That's strange, Kathy." She fixed me with a concerned look, which made me feel all the more worried.

"So you don't ever get like that."

She shrugged again. "Not so as I'd do it with just anybody. What you're saying does sound a bit weird, Kathy. But maybe it'll calm down after a while."

"Sometimes it won't be there for ages. Then it suddenly comes on. It was like that, the first time it happened. He started snogging me and I just wanted him to get off. Then suddenly it just came on, out of nowhere. I just really had to do it."

Ruth shook her head. "It does sound a bit weird. But it'll probably go away. It's probably just to do with the different food we're eating here."

She hadn't been a huge help, but she'd been sympathetic and I'd felt a little better about it all afterwards. That's why it was such a jolt to have Ruth suddenly bring it up the way she did in the middle of the argument we were having that afternoon in the field. Okay, there was probably no one to overhear us, but even so, there was something not at all right about what she'd done. In those first months at the Cottages, our friendship had stayed intact because, on my side at least, I'd had this notion there were two quite separate Ruths. There was one Ruth who was always trying to impress the veterans, who wouldn't hesitate to ignore me, Tommy, any of the others, if she thought we'd cramp her style. This was the Ruth I wasn't pleased with, the one I could see every day putting on airs and pretending--the Ruth who did the slap-on-the-elbow gesture. But the Ruth who sat beside me in my little attic room at the day's close, legs outstretched over the edge of my mattress, her steaming mug held in both her hands, that was the Ruth from Hailsham, and whatever had been happening during the day, I could just pick up with her where we'd left off the last time we'd sat together like that. And until that afternoon in the field, there'd been a definite understanding these two Ruths wouldn't merge; that the one I confided in before bed was one I could absolutely trust. That's why when she said that, about my "not being slow making friends with at least some of the veterans," I got so upset. That's why I just picked up my book and walked off.

But when I think about it now, I can see things more from Ruth's viewpoint. I can see, for instance, how she might have felt I had been the one to first violate an understanding, and that her little dig had just been a retaliation. This never occurred to me at the time, but I see now it's a possibility, and an explanation for what happened. After all, immediately before she made that remark, I'd been talking about the arm-slapping business. Now it's a bit hard to explain this, but some sort of understanding had definitely developed between the two of us about the way Ruth behaved in front of the veterans. Okay, she often bluffed and implied all sorts of things I knew weren't true. Sometimes, as I said, she did things to impress the veterans at our expense. But it seems to me Ruth believed, at some level, she was doing all this on behalf of us all. And my role, as her closest friend, was to give her silent support, as if I was in the front row of the audience when she was performing on stage. She was struggling to become someone else, and maybe felt the pressure more than the rest of us because, as I say, she'd somehow taken on the responsibility for all of us. In that case, then, the way I'd talked about her slap on the elbow thing could be seen as a betrayal, and she might well then have felt justified retaliating as she had. As I say, this explanation only occurred to me recently. At the time I didn't look at the larger picture or at my own part in it. I suppose, in general, I never appreciated in those days the sheer effort Ruth was making to move on, to grow up and leave Hailsham behind. Thinking about this now, I'm reminded of something she told me once, when I was caring for her in the recovery centre at Dover. We'd been sitting in her room, watching the sunset, as we so often did, enjoying the mineral water and biscuits I'd brought, and I'd been telling her how I still had most of my old Hailsham collection box safely stowed inside my pine chest in my bedsit. Then--I wasn't trying to lead onto anything, or make any kind of point--I just happened to say to her: "You never had a collection after Hailsham, did you?"

Ruth, who was sitting up in bed, was quiet for a long time, the sunset falling over the tiled wall behind her. Then she said: "Remember the guardians, before we left, how they kept reminding us we could take our collections with us. So I'd taken everything out of my box and put it into this holdall bag. My plan was I'd find a really good wooden box for it all once I got to the Cottages. But when we got there, I could see none of the veterans had collections. It was only us, it wasn't normal. We must all have realised it, I wasn't the only one, but we didn't really talk about it, did we? So I didn't go looking for a new box. My things all stayed in the holdall bag for months, then in the end I threw them away."

I stared at her. "You put your collection out with the rubbish?"

Ruth shook her head, and for the next few moments seemed to be going through in her mind all the different items in her collection. Finally she said: "I put them all in a bin bag, but I couldn't stand the idea of putting them out with the rubbish. So I asked old Keffers, once when he was about to drive off, if he'd take the bin bag to a shop. I knew about charity shops, I'd found it all out. Keffers rummaged in the bag a bit, he didn't know what any of it was--why should he?--and he did this laugh and said no shop he knew would want stuff like that. And I said, but it's good stuff, really good stuff. And he could see I was getting a bit emotional, and he changed his tune then. He said something like: ‘All right, missy, I'll take it along to the Oxfam people.' Then he made a real effort and said: ‘Now I've had a closer look, you're right, it is pretty good stuff!'

He wasn't very convincing though. I suppo............
