What are the man and the woman doing?

W: Jack! Slow down! It’s too dangerous to walk so fast. We’re going down hill.
M: Don’t worry. Oh, no, my foot.
W: What happened?
M: I’ve sprained my ankle! It hurts a great deal.
W: Which one?
M: The fight one.
W: Oh. It’s already swollen. Let me give you massage.
M: Massage?
W: Yes. I learned it from my grandma.
M: Oh. It hurts a lot.
W: Be relaxed. You’ll feel better soon.
M: Ah! Much better now. Thank you !
