#Person1#: But I have to say goodbye right now.
#Person2#: Why? It's not late. Can't you stay a little longer?
#Person1#: No, I'm sorry, but I really must go. I don't know whether I can catch the last bus if I don't hurry now.
#Person2#: When does the bus go?
#Person1#: At ten o'clock. Oh dear! It's already a quarter past ten.
#Person2#: Don't worry, Kate. Since you have missed the bus, it is unnecessary for you to hurry. I can drive you home.
#Person1#: Thank you. You are so kind. But my mother will worry about me if I'm too late getting home. I must get home before 11:00.
#Person2#: That's all right. Let's go now. But I hope to have a chance to see you again.
#Person1#: Thank you, John.
