Tony: Can we go to the game on Saturday?
Daisy: I’m sorry, I can’t. I’m going to meet my sister.
Tony: Why don’t you bring your sister?
Daisy: Thanks, but we can’t. We must buy a gift for my Mom’s birthday.
Tony: And after that?
Daisy: Well, I have to make cookies for the party.
Tony: Can we go out in the evening?
Daisy: I’d love to. But I have to pick up my cousins at the station.
Tony: How about Sunday?
Daisy: Sorry. I have to look after my little brother.
