You look worried, Mary. What can I do for you?
I've lost my shoulder bag, John.
Are you sure you've searched everywhere?
Yes, I can't find it anywhere.
Can you tell me something about it?
Yes. It's brown leather and it has a button on the front.
What was in it?
My wallet with twenty pounds in it, er ...some keys, and an English dictionary.
When did you last have it?
I had it with me at lunch time in the restaurant. I hung it on the side of my chair while I was eating.
When did you find it was missing?
After lunch, I was going to buy something but I couldn't find my bag. I realized I had left it in the restaurant. I went back to get it, but it wasn't there on the chair.
