hilarious on books

I was reading the book that i mentioned the other day, and there is a section in it on understanding time and space. And he was noting how people think about different categories . . . and was remarking (yeah, i'll get to it) a about cognitive psychologist roger shepard who obsreved
that "people often wish that they had an office with additional space, so they would have more places to put their books. But they never wish they had an office with additional dimensions, so they would have more ways to arrange their books.

I was giggling at the trolley stop
