W: Where do you think you lost the wallet?
M:I don’t have any idea. I had an appointment with Dr. Baker at nine o’clock.
W: What time did you leave his office?

W: Isn’t it possible that it could have slipped out of your pocket in the taxi?
M:I just don’t know. Anyway, I could never find that same taxi again.
