Look, Bob. This is a photograph I took during my trip to Australia.
Let me see it, can I? This is a good photograph. Who are these people?
They're people I met during the trip. That's the ship we traveled on.
What a beautiful ship! Who's this?
That's the man I told you about. Remember?
Ah yes. The one who offered you a job in Australia.
That's right.
Who's this?
Guess!
It's not you, is it?
That's right. I grew a beard during the trip, but I shaved it off when I came home.
Why did you shave it off?
