Christopher would like to be an astronaut, and he thinks he would be good at it because he understands machines, he likes being in small spaces, and he wouldn’t have to talk to many people. Sometimes he looks up at the sky and pretends he’s all alone in space. He hopes he might be allowed to bring his rat, Toby, into space too.
Christopher’s large ambitions come to light again, along with his awareness of his differences—but he sees these differences as advantages that make him a prime candidate to be an astronaut. Furthermore, he reveals a deep attachment to his pet rat that makes Toby his sole companion of choice.
