W: What do you usually do on Saturday?
M: Well, I usually visit my aunt. She lives alone and doesn’t have many friends.
W: Do you visit her every Saturday?
M: I try to. She is quite old and can’t walk very far, so I often do some shopping for her.
W: Does she live near the shops?
M: Yes, but she finds it difficult to carry heavy things because of her poor health. There is something wrong with her left leg.
W: Did she have an accident?
M: Oh, no. I think it’s just because she is old.
