20. Mailbox Key Missing

A: Have you seen my mailbox key lying around somewhere?

B: No, I'm sorry. Where did you last leave it?

A: I thought it was in my pocket.

B: Is that where you last put it?

A: Yeah, I'm pretty sure.

B: Think hard. Where was it before you supposedly put in your pocket?

A: I was in my apartment cleaning out the kitchen.

B: Maybe you emptied your pockets while you were cleaning.

A: Wait! I think I did empty my pockets!

B: There you go. I knew it.

A: I remember now. My keys are on the kitchen counter.

B: That's a relief.
