Rodney, who had a driver's licence, had made an arrangement to borrow a car for the day from the farm-workers at Metchley a couple of miles down the road. He'd regularly got cars this way in the past, but this particular time, the arrangement broke down the day before we were due to set off. Though things got sorted out fairly easily--Rodney walked over to the farm and got a promise on another car--the interesting thing was the way Ruth responded during those few hours when it looked like the trip might have to be called off.

Until then, she'd been making out the whole thing was a bit of a joke, that if anything she was going along with it to please Chrissie. And she'd talked a lot about how we weren't exploring our freedom nearly enough since leaving Hailsham; how anyway she'd always wanted to go to Norfolk to "find all our lost things." In other words, she'd gone out of her way to let us know she wasn't very serious about the prospect of finding her "possible."

That day before we went, I remember Ruth and I had been out for a stroll, and we came into the farmhouse kitchen where Fiona and a few veterans were making a huge stew. And it was Fiona herself, not looking up from what she was doing, who told us how the farm boy had come in earlier with the message. Ruth was standing just in front of me, so I couldn't see her face, but her whole posture froze up. Then without a word, she turned and pushed past me out of the cottage. I got a glimpse of her face then, and that's when I realised how upset she was. Fiona started to say something like: "Oh, I didn't know..." But I said quickly: "That's not what Ruth's upset about. It's about something else, something that happened earlier on." It wasn't very good, but it was the best I could do on the spur of the moment.

In the end, as I said, the vehicle crisis got resolved, and early the next morning, in the pitch dark, the five of us got inside a bashed but perfectly decent Rover car. The way we sat was with Chrissie up front next to Rodney, and the three of us in the back. That was what had felt natural, and we'd got in like that without thinking about it. But after only a few minutes, once Rodney had brought us out of the dark winding lanes onto the proper roads, Ruth, who was in the middle, leaned forward, put her hands on the front seats, and began talking to the two veterans. She did this in a way that meant Tommy and I, on either side of her, couldn't hear anything they were saying, and because she was between us, couldn't talk to or even see each other. Sometimes, on the rare occasions she did lean back, I tried to get something going between the three of us, but Ruth wouldn't pick up on it, and before long, she'd be crouched forwards again, her face stuck between the two front seats.

After about an hour, with day starting to break, we stopped to stretch our legs and let Rodney go for a pee. We'd pulled over beside a big empty field, so we jumped over the ditch and spent a few minutes rubbing our hands together and watching our breaths rise. At one point, I noticed Ruth had drifted away from the rest of us and was gazing across the field at the sunrise. So I went over to her and made the suggestion that, since she only wanted to talk to the veterans, she swap seats with me. That way she could go on talking at least with Chrissie, and Tommy and I could have some sort of conversation to while away the journey. I'd hardly finished before Ruth said in a whisper: "Why do you have to be difficult? Now of all times! I don't get it. Why do you want to make trouble?" Then she yanked me round so both our backs were to the others and they wouldn't see if we started to argue. It was the way she did this, rather than her words, that suddenly made me see things her way; I could see that Ruth was making a big effort to present not just herself, but all of us, in the right way to Chrissie and Rodney; and here I was, threatening to undermine her and start an embarrassing scene. I saw all this, and so I touched her on the shoulder and went off back to the others. And when we returned to the car, I made sure the three of us sat exactly as before. But now, as we drove on, Ruth stayed more or less silent, sitting right back in her seat, and even when Chrissie or Rodney shouted things to us from the front, responded only in sulky monosyllables.

Things cheered up considerably, though, once we arrived in our seaside town. We got there around lunch-time and left the Rover in a car park beside a mini-golf course full of fluttering flags. It had turned into a crisp, sunny day, and my memory of it is that for the first hour we all felt so exhilarated to be out and about we didn't give much thought to what had brought us there. At one point Rodney actually let out a few whoops, waving his arms around as he led the way up a road climbing steadily past rows of houses and the occasional shop, and you could sense just from the huge sky, that you were walking towards the sea.

Actually, when we did reach the sea, we found we were standing on a road carved into a cliff edge. It seemed at first there was a sheer drop down to the sands, but once you leant over the rail, you could see zigzagging footpaths leading you down the cliff-face to the seafront.

We were starving by now and went into a little café perched on the cliff just where one of the footpaths began. When we went in, the only people inside were the two chubby women in aprons who worked there. They were smoking cigarettes at one of the tables, but they quickly got up and disappeared into the kitchen, so then we had the place to ourselves.

We took the table right at the back--which meant the one stuck out closest to the cliff edge--and when we sat down it felt like we were virtually suspended over the sea. I didn't have anything to compare it with at the time, but I realise now the café was tiny, with just three or four little tables. They'd left a window open--probably to stop the place filling up with frying smells--so that every now and then a gust would pass through the room making all the signs advertising their good deals flutter about. There was one cardboard notice pinned over the counter that had been done in coloured felt-tips, and at the top of it was the word "look" with a staring eye drawn inside each "o." I see the same thing so often these days I don't even register it, but back then I hadn't seen it before. So I was looking at it admiringly, then caught Ruth's eye, and realised she too was looking at it amazed, and we both burst out laughing. That was a cosy little moment, when it felt like we'd left behind the bad feeling that had grown between us in the car. As it turned out, though, it was just about the last moment like that between me and Ruth for the rest of that outing.

WE HADN'T MENTIONED THE "POSSIBLE" at all since arriving in the town, and I'd assumed when we sat down we'd finally discuss the matter properly. But once we'd started on our sandwiches, Rodney began talking about their old friend, Martin, who'd left the Cottages the year before and was now living somewhere in the town. Chrissie eagerly took up the subject and soon both veterans were coming out with anecdotes about all the hilarious things Martin had got up to. We couldn't follow much of it, but Chrissie and Rodney were really enjoying themselves. They kept exchanging glances and laughing, and although they pretended it was for our benefit, it was clear they were remembering for each other. Thinking about it now, it occurs to me the near-taboo at the Cottages surrounding people who'd left might well have stopped them talking about their friend even to each other, and it was only once we'd come away they'd felt able to indulge themselves in this way.

Whenever they laughed, I laughed too just to be polite. Tommy seemed to be understanding things even less than me and was letting out hesitant little half-laughs that lagged some way behind. Ruth, though, was laughing and laughing, and kept nodding to everything being said about Martin just like she too was remembering them. Then once, when Chrissie made a really obscure reference--she'd said something like: "Oh, yes, the time he put out his jeans!"--Ruth gave a big laugh and signalled in our direction, as though to say to Chrissie: "Go on, explain it to them so they can enjoy it too." I let this all go, but when Chrissie and Rodney started discussing whether we should go round to Martin's flat, I finally said, maybe a bit coldly: "What exactly is he doing here? Why's he got a flat?"

There was a silence, then I heard Ruth let out an exasperated sigh. Chrissie leaned over the table towards me and said quietly, like she was explaining to a child: "He's being a carer. What else do you think he'd be doing here? He's a proper carer now."

There was a bit of shifting, and I said: "That's what I mean. We can't just go and visit him."

Chrissie sighed. "Okay. We're not supposed to visit carers. Absolutely strictly speaking. Certainly not encouraged."

Rodney chuckled and added: "Definitely not encouraged. Naughty naughty to go and visit him."

"Very naughty," Chrissie said and made a tutting noise.

Then Ruth joined in, saying: "Kathy hates to be naughty. So we'd better not go and visit him."

Tommy was looking at Ruth, clearly puzzled about whose si............
