Why is Grace calling John?

W: Hello, may I speak to John please?
M: Speaking! Who’s that?
W: It’s Grace here. How have you been?
M: Oh, hi, Grace! I’m fine! Thanks.
W: I’m calling to invite you to dinner this Saturday in my house. Are you free then?
M: Sure! And I’d love to come. By the way, is this Saturday a special occasion?
W: Oh, you can say so. I’m moving out on Sunday, so I invite all my good friends to have a farewell dinner in my house.
M: You are moving out! I can’t believe it. It is so sudden!
W: Yes, it may sound a bit sudden. I bought a new apartment.
M: Congratulations! So, what is your new apartment like?
W: It is a newly built apartment, 3 blocks away from my present place. I live on the top floor—that is to say on the 16th.
M: That sounds great! But don’t you feel it is a bit too high? You know, on the top!
W: That’s exactly why I love the apartment! There’s a roof garden for each top layer apartment. The light condition is also very good there.
M: Oh, there is a garden! How amazing!
W: And the window view is also very nice! I can see the mountains far away! After I settle down there I will sure invite you to come!
M: I’m looking forward to that! What about your parents? Do they live with you?
W: Oh, no. They will go back to the hometown. They can’t adapt to the life here and they miss their good old friends and the fresh air.
M: Oh, that’s my dream life after my retirement. Well, if you need someone to help you with the moving, I’ll be there!
W: No, I’ve already made my arrangement. Thanks anyway! But if you are free on Saturday afternoon, could you please come and help me with the cooking? My friends love your recipes. But if you are not, never mind! That’s all I ask!
M: Sure! I’ll see you then!
