 Much to Tim s horror, Martin suggests that Earth children should be deep-frozen until adulthood. This act, he surmises, would spare them the unhappiness of being relatively unproductive, not fully formed beings. Since Tim says Martin is being unscientific by not having this theory proved, Martin wants to test his theory on an Earth child. He decides to at least observe a child, a problem child at that, and enlists the aid of an orphanage which has an out-child program. His charge, Doris, ends up being someone with whom he has a lot of fun and visa versa. However she eventually sees differently when she stumbles on his report on her/deep-freezing and the fact that she is just an experiment to him. So Doris runs away. But after Martin finds her, he admits that he was wrong about the sadness and non-productivity of children and wrong to use Doris, a precious person, as an experiment.
