Among the many quirks I have, is the display of my "TBR" and "Read" piles. And although my husband says that my reasonings are completely lost on him, I cannot feel anything but content with my odd habit.
See, I have a lovely little "nook" in my home that's kind of all mine. It contains my music and a couple bookshelves and an old wing-back chair. It has my husband's photography on the walls, and a few guitars and I absolutely love it. This is where these piles live.
I like to see my TBR pile each day. I dream about what the covers might have to tell about the stories within. I prefer to select my next book based purely on emotion, instead of any obligations or blog-timelines. So naturally, stacking them all together where they're easy to see and get at just makes good sense.
The reason I have for stacking my "read" books as well is twofold. To start, once I'm done with a story or set of characters, I find it hard to just put them away on a shelf as though they meant so little. (at least not right away) I love to walk pass them and remember scenes and how they made me feel or remember quotes that might have had an effect on me. Secondly, by keeping them out it's easier when a friend pops over to borrow that book I kept telling them they "had to read".
The addition of the ipad this year has censored the habit slightly, but I must admit that I'd be sad if my 2 little piles of books ever went away completely.
