I can NOT go into a bookstore without coming away with a book or two, so my living spaces are always inordinately cluttered. :)
But I have often bought them without any further intention, or time, to read them twice, and so I either give them away as gifts or sell them. Thus I have room for more books, and when I'm done with those, the cycle lives on! Make me an offer, and I can part with these babies. Viva las previously-enjoyed books!
