Amy: Hello, Sarah. I'm going to the post office.
Sarah: What do you want to do there?
Amy: I want to buy a postcard. Would you like to go with me?
Sarah: Certainly! Where is it?
Amy: It's next to the museum. There is a kite show in the museum today, and we can go and have a look.
Sarah: Great! When?
Amy: At 3:00 in the afternoon. We can meet at the school gate.
Sarah: OK. See you then.
Amy: See you.
