Ann : Look, Harry! That policeman's waving to you. He wants you to stop.
Policeman : Where do you think you are? On a race track? You must have been driving at seventy miles an hour.
Harry : I can't have been.
Policeman : I was doing eighty when I overtook you.
Policeman : Didn't you see the speed limit?
Harry : I'm afraid I didn't, officer. I must have been dreaming.
Ann : He wasn't dreaming, officer. I was telling him to drive slowly.
Harry : That's why I didn't see the sign.
Policeman : Let me see your driving-license and your insurance certificate.
Policeman : I won't charge you this time. But you'd better not do it again!
Harry : Thank you. I'll certainly be more careful.
Ann : I told you to drive slowly, Harry.
Harry : You always tell me to drive slowly, darling.
Ann : Well, next time you'd better take my advice!
