One of the first things I do when I find myself at someone's house is start poking through their bookshelves. Partly it's curiousity about the bookshelf-owner -- do they like Jane Austen? Do they own a copy of The Story of O? And part of it is that I'm just plain addicted to reading. I can't go a day without it, and can't have any text in front of me without wanting to read it.
When I was a kid, my mom would often ask me to clear the table for dinner, only to find me a half and hour later, completely absorbed in the leftover newspapers from breakfast. I'm the world's slowest filer, too -- do you have any idea the things that get stuck in files? They're facscinating. And don't get me started on the internet -- for every hour of research I do, I spend at least two hours on blogs or wikipedia or true life ghost story pages.
Anyway. Here's a picture of my bookshelf (the one in the living room, by the front door):
