person A: I had surgery a few weeks ago. It was tough_comma_ but my friends really helped out.
person B: Oh my_comma_ what did you have surgery for?
person A: My knee. But what's important is that my friends brought over dinner for a week so I wouldn't have to cook. They're really wonderful and I'm very lucky to have them as friends.
person B: That's really nice! I hope you recover really quick!
