The vast majority of my friends are nonreaders, or very close to that (maybe one book a year). I don't mind. I actually don't really like to talk about books much anyway, so it's not like I find myself unable to communicate with them. The ones that do read tend to read only the bestsellers they hear about through Oprah or friends or whatnot, so I don't always have anything to say about those books anyway.
I'd consider my husband a nonreader, although that's probably not completely true. He does occasionally read a non-fiction book, and he reads Time magazine (in the bathroom). He doesn't really see the point of fiction, and to me, that constitutes a nonreader
He doesn't see stories in his head when he reads fiction, he thinks it's a waste of time. I read plenty of nonfiction, but I really like the escape that fiction offers, amongst other things. So we differ on that account. We actually differ on a lot of accounts, but that's ok by me. I don't need another one of me in the house.
