This is when I was living in Japan.
I’m expecting my (Australian) friend any minute and decide to surprise him by opening the door and mooning him.
The doorbell rings, I swing the door open as I turn around and trump trou.
I hear a throat clear and look back.
There are two Japanese Jehovah’s Witnesses at my door.
They shove a pamphlet in my hand, turn around, and mumble something about coming back later as they scurry away.
A minute later my friend walks in and I tell him the story.
He says he saw two people laughing as they walked away from my apartment.
