When I was a teenager I didn't always have a book available, and I was an insatiable reader. So I would go to my father and ask if he had a book to spare. He was always going on business trips and read whenever he was on a plane. Frequently, he would ask me not to lose his place, and he would tell me when his next trip was so I could get it back to him, and then he could pick up where he left off. I read science fiction, and he read action adventure, but to me a book was a book was a book. If it had words placed in sentences, I was going to read it.
