What is the probable relationship between the man and the woman?

M: Oh, Anna, that’s a wonderful dinner. That’s the best meal that I’ve had in a long time.
W: Oh, thank you, thank you very much.
M: Can I give you a hand with the dishes?
W: Oh, don’t bother. I’ll do them myself later. Hey, would you like me to fix some coffee?
M: Oh, thanks a lot. I’d love so. Eh, would you mind if I smoked?
W: Why? Not at all. Here, let me get you an ashtray.
M: Oh, thanks very much. Anna, I didn’t realize you were such a good cook.
W: Actually, I’ve just learned how, you know. It’s because I’ve been taking these courses.
M: Why? I can’t cook at all. Can’t even boil an egg.
W: No kidding? Well, you know, if you want to, you could take a couple of classes over at Podun College and learn how to do it, too.
M: Thanks a lot. But I’m pretty busy these days. Oh, I just remembered. I wonder if I could possibly use your phone.
W: Oh, I’m sorry. But it’s out of order. Is it really important?
M: Well, you see, I have to call my foreman about tomorrow’s work schedule. Excuse me, would you mind if I just went out for a few minutes? I’ll call him at the phone booth on the comer.
W: Not at all. So long as you know your way back.
