Hari Seldon said, "It is beautiful outside-a marvelous evening. Considering that we live under a dome, you would think we would have beautiful weather like this every evening."
    Wanda said indifferently, "We would grow tired of it, Grandpa, if it were beautiful all the time. A little change from night to night is good for us."
    "For you, because you're young, Wanda. You have many, many evenings ahead of you. I don't. I want more good ones."
    "Now, Grandpa, you're not old. Your leg is doing well and your mind m as sharp as ever. I know. "
    "Sure. Go ahead. Make me feel better." He then said with an air of discomfort, "I want to walk. I want to get out of this tiny apartment and take a walk to the Library and enjoy this beautiful evening."
    "What do you want at the Library?"
    "At the moment, nothing. I want the walk. -But .    "
    "Yes. But?"
    "I promised Raych I wouldn't go walking around Trantor without a bodyguard."
    "Raych isn't here."

It was both heavier and stronger than his old cane and, if he was going to have none other than Wanda as a bodyguard, he thought he had better bring his new cane.
    The walk was delightful and Seldon was terribly glad he had given in to the temptation-until they reached a certain spot.
    Seldon lifted his cane in a mixture of anger and resignation and said, "Look at that!"
    Wanda lifted her eyes. The dome was glowing, as it always did in the evening, in order to lend an air of first twilight. It grew darker as night went on, of course.
    What Seldon was pointing at, however, was a strip of darkness along the dome. A section of lights had gone out.
    Seldon said, "When I first came to Trantor, anything like that was unthinkable. There were people tending the lights at all times. The city worked, but now it is falling apart in all these little ways and what bothers me most is that no one cares. Why aren't there petitions to the Imperial Palace? Why aren't there meetings of indignation? It is as though the people of Trantor expect the city to be falling apart and then they find themselves annoyed with me because I am pointing out that thi............
