I used to complain that there were not enough bookstores in Beijing, and there were no good books to buy inside. I often spent half a day in a bookstore without finding a book that I wanted to buy and read at one go. Frequently, after I left the bookstore, I would think that I should buy a few books, otherwise it would be like I had wasted my time. So I would turn back and buy a pile of books that I might read when I am old, but I guess when I get old, I probably won't read them either.
