A book that is shut is but a block. -Thomas Fuller (http://www.quotegarden.com/books.html)
I'm the type of person that can be found at lunch hunched up against a wall reading. When I find a book I really like I might even walk into a few walls trying to get there.
If you're not going to read a book I'd recommend buying a block instead, chances are it's cheaper. Books are meant to be read and, unless you plan on hitting someone with a particularly heavy one, there isn't much else you can do but read them.
