When Alan was young, he played a lot of football, and he was very good at it, but then he went and worked in a town, and there was no team for him there, so he stopped playing.
Then he began to get rather fat, so he thought, “I’ve stopped playing football, and now I’m getting fat. What am I going to do?” He thought about it for a few days, and then he said to himself, “I know: I’ll play tennis.”
He had a few lessons, and then played for a few months.
He met a girl at the tennis club one day, and they played a game of tennis against another young man and woman. Alan played very badly, and was very angry with himself, “I’ve never played as badly as this before,” he said to the girl.
“Oh,” she said, “you have played before, have you?”
