W: Good morning.
M: Morning, can I help you?
W: Yes, I’d like to join the library. We’re new to the district you see.
M: Certainly. Well all we need is some sort of identification with your name and address on it.
W: Oh . We just moved, you see, and everything has my old address.
M: A driving license, perhaps?
W: No, I don’t drive.
M: Your husband’s would do.
W: Yes, but on his license is still the old address.
M: Perhaps you have a letter addressed to you at your new house?
W: No, I’m afraid not. We’ve only been there a few days you see and no one’s written to us yet.
M: What about your bank book?
W: That’s just the same. Oh dear, and 1 did want to get some books out this weekend. We’re going on holiday to relax after the move, you see, and I want to take something with me to read.
M: Well, I’m sorry, but we can’t possibly issue tickets without some form of identification. What about your passport?
W: What? Oh yes, how silly of me. I’ve just got a new one and it does have our new address. I’ve just been to book our tickets so I have it on me. Just a minute. Here you are.
M: Thank you. Well, that’s all right. Now if you’d like to go and choose your books your tickets will be ready for you when you come back to the desk to have them stamped out.
W: Oh, thank you.
