Peter: You're not bringing a bag, are you? We're only going for one night!
Me: Just a small bag.
Me: Carry-on size. I have to carry our winter coats.
Peter: We can wear them on the train.
Me: I am not sleeping on the train all night in a down overcoat.
Peter: Why not? It's like a sleeping bag.
Peter: Who will be carrying this alleged bag?
Me: You. You're the man.
Peter: Americans are too difficult. Like math.
