Why not join the club I am in? ,M: Is it far from our neighborhood? ,F: No, it's just 10 minutes away from here by bike. ,M: What do you do there? ,F: Well, I often start out running for about half an hour and then I get in the swimming pool for an hour. ,M: I really like swimming. It's a good way to lose weight, isn't it? ,F: Oh, it certainly is. I was 135 pounds when I joined the club. Now I weigh just 120 pounds, and I'm sure I'll manage to lose another 10 pounds by the end of July. ,M: That's amazing. Perhaps I'll go and have a look at your club tonight.

How do you spend your spare time then, Lily? ,F: Playing the piano is my favorite activity. ,M: Our hobbies are similar to each other. I hope we can often exchange experiences together. ,F: So do I, but I'm weak in the theory of music.
(A) M: It doesn't matter.Anyway, I can't believe that our hobbies are same:going to concerts. (B) M: Oh, me too.
