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.
