     Fishing is my favorite sport. I often fished for hours without catching anything, and this doesn’t worry

me. Some fishermen are unlucky. Instead catching dish, they catch old boots and rubbish. I’m even less

luck. I never catch everything---even old boots after having been spent a whole morning in the river. So

I always go home with empty bag. “You should give up fishing,” my friends say, “It’s a waste of time.”

But they don’t realize one important thing. I’m not real interested in fishing. I’m only interested in sitting in

a boat and do nothing at all.
