Why did Shelly call?

M: Hello.
W: Hello, Dad?
M: Yes... Shelly! How are you? Is there anything wrong?
W: Oh, no. I’m just calling to see how you and Mom are. It’ s been quite a while since I saw you last.
M: Oh, we’ re both fine. Your mother is down at the new shopping center shopping.
W: For a new dress?
M: No, for shoes this time. How’ s Tom?
W: He’ s fine. He likes his work and was given a raise last month by Mr. Davis. We were all pretty pleased about that.
M: Yes, I think you should be. And how are the children?
W: Well, Billy’ s at home from school today. It’ s nothing serious, just a bad cold and it’ s his birthday, too.
M: Oh, I thought his birthday was May 24th.
W: No, the 23rd.
M: Well, that’ s too bad. Tell him we sent him a present.
W: All right. Sally’ s still taking dancing lessons.
M: She must be pretty good by now. I’ d like to see her sometime. And how’ s Ted?
W: He’ s OK, too. He loves working on cars and has a part-time job at the garage now.
M: Well, it’ s certainly good to hear your voice. When are you coming for a visit?
W: Not for a few months, t’ m afraid. But I hope we can come for a few weeks this summer, probably in July.
M: That would be nice. Call again soon.
W: OK, Dad. Nice talking to you and glad everything’ s all right. Give Morn our love.
M: All right. Goodbye.
W: Goodbye, Dad.
