A: Do you know John's address?

B: No, I don't. Why do you need it?

A: I want to invite his son to my daughter's party.

B: Wow, how old will she be?

A: She will be four next week.

B: Children grow like weeds.

A: Yes, they do. His son is almost five now.

B: Why doesn't she give it to him at school?

A: I am afraid one of them will lose it.

B: Send John a message and ask him his address.

A: I guess I will have to.

B: Either way, I'm sure they will come to the party.
