My name is Huy and fishing is my favorite sport. I often fish for hours without catching anything. But this doesn't worry me. Some fishermen are unlucky. Instead of catching anything, not even old boots. After spending the whole morning on the river, I always go home with an empty bag. "You should give up fishing", my friends say. " It's a waste of time". But they don't know that I'm not really interested in fishing. I'm only interested in sitting in a boat and doing nothing at all!
