It was a Sunday morning when finally I decided to organize some books that had been scattered in cartons for a long time. I wanted to put them on the bookshelf, when I saw three books that were not mine. I was surprised! Those books brought back memories when I was a boy in high school. I was remembering that I had borrowed those books a long time ago and never returned to their owner. Sure, the owner of the books forgot about loaning them to me. Can you imagine a book loaned for over 10 years?
