A boy, his family, and other families are traveling in space when his cryogenic chamber malfunctions. He essentially lives with only robots for company for 70 years or so. I remember that they always let him win at chess. When his family awakens, they are shocked to see how he aged.
Then I impulsively skipped ahead


SPOILER
He goes back into a chamber.
