"A desire to actually get sleep instead of animals disagreeing and then having to listen to the complaints of the owner is a good reason." The downside of shared space. It wasn't really viable to add another animal to an already crowded room that's overflowing with other people's belongings.

Personal space happens in OTHER places. Not on the train.

The idea of names draws a shrug. "I haven't thought that far ahead." Names were pretty individual things! "It would be hard to pick out a name without knowing anything about a creature besides its species."
