FATHER:    What are you going to do this evening,  Betty?

Betty:            I'm going to meet some friends, Dad.

FATHER:        You mustn't come home late. You must be home at half past ten.

BETTY:         I can’t get home so early, Dad.

Can I have the key to the front door, please?

FATHER:        NO, you can't.

MOTHER:    Betty's eighteen years old, Tom. She's not a baby. Give her the key. She always comes home early.

FATHER:        Oh, all right!

FATHER:   Here you are.   But you mustn't come home after a quarter past eleven. Do you hear?

BETTY:        Yes, Dad.

BETTY:        Thanks, Mum.

MOTHER:       That's all right. Goodbye. Enjoy yourself!

BETTY:        We always enjoy ourselves, Mum. Bye, bye.
