Cera writes about unread books. Years ago, I got a book on how to reduce clutter, and under “Books”, it said something about all the unread books people have, and how this is clutter.
I have no unread books. When I acquire a book, I read it. Then I put it on the bookshelf. Later, maybe (ok, probably), I read it again.
Why does anybody have unread books? Do you have unworn clothes, too?

A few of both, and for the same reason: gifts. Too guilty to get rid of ’em.
Ok, I can see that, except that I’m not too guilty to re-gift.
