But I think somebody gave the surprise away. M: Who would do anything like that W: Mrs. Sampson might. You know she can’t keep a secret. And she and Nancy are such good friends. M: Didn’t you warn her to be careful about what she said W: I told her not to say a word. M: Well, surprise or not, I’m sure Nancy had a good time. She was smiling and laughing all evening. W: And crying a little too. She asked everyone to come and visit her in New York. M: And everyone was asking her to write or to call, or best of all, to come back’. W: We’re all going to miss her. Just about everybody in the office working for Nancy in the correspondence section. M: Yes, and she is a true friend and always tries to help everyone. W: It won’t be too long before I see her again. I’m going to New York next month, and she invited me to stay with her. M: That’ll be wonderful. Anyway, she’s still working with the same company. So I’m sure we’ll get to talk to each other on the phone pretty often.11.What happened to Nancy
