Query: Flowers For Algernon

When I read Charlie I thought it was going to be a bad book, I thought I thought it was going to be about a guy that had mental problems. But instead it was a very interesting book about human feelings and human nature; it showed all that he had to become smarter. It was fascinating, because all of the different things he suffers to become intelligent. I think it that is very impressive how a human being has this obsession and tries to overcome it. It is fascinating and impressive. Even though it is a fiction book it is very realistic and human, and shows both sides of the human nature, (when he was retarded, and when he was smart). I really liked this book and I really recommended to anyone that wants to have a good read.
