“Solitude” was written because I wanted to write about an introvert who finds a good place for introverts to live. Clearly it had to be on another world, because the World As We Know It is filled almost solid with extraverts, who refuse to learn how to spell “extravert” because they’re too busy rushing around in crowds shouting and cellphoning and texting and friending and joining groups and being outgoing and sociable to pay any attention to stuff like Latin prefixes, or silence, or introverts.”
