You look worried. What's happened? I've lost my wallet. I've looked everywhere, in my bag, in my coat, in the car, and I can't find it. Oh no. When did you last have it? This morning. I paid for a coffee at the station at about half past eight. Then I went to the library and spent two hours there. Did you take it out in the library? I don't think so. I bought a sandwich on the way back, but I paid with my phone. Have you called the library? Not yet. I've only just got back. Well, call them now. And have you cancelled your bank card? Yes, I've already done that. I did it on the bus. Good. Has anyone tried to use it? No, nothing has happened so far. I checked the app ten minutes ago. Then don't panic. Someone has probably found it already.
