A: Hi, this is Lucy. Can I talk to Ellen
B: Hi, I do not know Ellen.
A: Sorry, is this Colin's home?
B: No, it's not. Are you sure you dial the right number?
A: I think so. I dialed 021-005621.
B: That's my number. It's so weird.
A: This is the number one of my friends gave me. She said it's the number of her home.
B: I bet it's been a long time since you called this number last time.
A: Not really, less than a year.
B: That's right. I just moved in one month ago.
A: OK, do you happen to know Ellen Colin? I think she moved out before you moved in.
B: Let me ask my mother. She might know. Hold on. Hi, my mother knows Ellen and she said Ellen had moved to New York. And here is her new number: 212-005548.
A: Thanks for your help.
B: You're welcome.
