Have you seen my coat? I am going to have to go down to the shop for more bread.
Why?
I'm not sure what happened. I made some sandwiches earlier and left them on the table when I went to answer the phone. But someone must have taken them, because they're gone.
Oh, it must have been dad. I'm sure he was in the kitchen earlier.
No, he went off to his tennis match before I finished making them, so he couldn't have done it. Anyway, he couldn't carry a plate of sandwiches as well as his tennis stuff, so I'm sure it wasn't him.
Well, it wasn't me. But look, are these your sandwiches here, on the bottom shelf of the fridge?
Are they there? Oh, my goodness, I must have put them there when the phone rang. Oh dear, I really must be losing my mind.
Well, you needn't go to the shop now. Let's have lunch.
