Lesson 20 One man in a boat
Fishing is my favorite sport. I often fish for hours without catching anything. But this does not worry me. Some fishermen are unlucky. Instead of catching fish, they catch old boots and rubbish. I am even less lucky. I never catch anything-not even old boots. After having spent whole mornings on the river, I always go home with an empty bag. 'You must give up fishing!' my friends say.' It's a waste of time.' But they don't realize one important thing. I'm not really interested in fishing. I am only interested in sitting in a boat and doing nothing at all!
