Father: Why is Tania crying?

Mother: She just lost her wallet.

Father: Really?

Mother: Yes. I think I am going to ask her to go shopping, so that she will forget about her wallet.

Father: Brilliant. You could buy her a new wallet too.

Mother: Oh, okay. I almost forget about that.

Father: Why don't you make a list of things that you want to buy?

Mother: Okay, that's a good idea, so I won't miss any important things.

Father: Yes. By the way, do you want me to take you to the market?

Mother: Can you? Aren't you busy?

Father: I am busy, but I want to cheer her up, too.

Mother: Thank you. Okay, we will leave at seven.

Father: Okay.
