One fine Sunday morning, Robert would like to go fishing in a river nearby. He says goodbye to his mother and goes out. When he gets to the river, he finds some other boys there. They try to catch fish, but there are not a lot of fish in the river. Robert catches only one. Happily, he puts it into his jar with some water.
In the afternoon, he sees more fish in the river. Quickly he takes off his shoes and walks into the water. He put his nets into the river. But the fish swim away. When he gets back to the jar, he doesn’t see the fish.
He gets home late with nothing in the jar. His mother asks him, “Do you have a good time?” Robert answers, “No, but the fish does.”
