[speaker001:] Does your girl friend like swimming?
[speaker002:] Yes, she does. She is good at backstroke and free style.
[speaker001:] Then you can help her with the breaststroke and sidestroke.
[speaker002:] But she wants to learn the butterfly stroke
[speaker001:] Really? Then just ask her to follow me.
[speaker002:] I heard you are now practicing underwater swimming, aren't you?
[speaker001:] Yes. But I still have some difficulties it breathing.
[speaker002:] Say, kid, keep on practicing, you're sure to be a first-class swimmer.
[speaker001:] To tell you the truth, I have never thought of being a swimmer. I swim just for fun.
[speaker002:] That's good.
