I've never reread a book that I've finished before. Lately I've been getting into the habit of reading more for the first time in a long time and now there are a handful of books which I've recently finished. That makes me start to consider rereading some of the books I've enjoyed so I could feel like I've retained them better, since I'm usually not going to remember details of a book after I've finished it for the first time unless the book was short or the book had parts that really fascinated or impressed me. It just bothers me to have a list of books that I've finished and feeling like what I read went in one ear and out the other. So why do you reread books? How often do you reread books and how quickly after you finish a book do you reread it?
