Small talk.
We are in the kitchen.
I am cooking potatoes and admiring the reflection of my new haircut in the window.
I see a strobe type effect in a window of the building opposite.
"Look, they are having a discotheque," I say to hub.
He looks.
"There's a man in that building," replies hub.
"Yes," I say (encouragingly).
"And he watches me while I am out the back having a cigarette."
"Strangely."
"How exactly are you smoking?" I enquire (I am quite the wit).
"It could be because once, when I was a bit drunk, I did something," he continues, ignoring my hilarious joke.
There is a pause.
"You did something," I say, encouragingly again. (He can be a bit reticent.)
"Yes," he says.
"Right," I say.
"This," he says.
And he entirely pulls his trousers down and shows me his bottom.
"Yes," I say, "That would account for it."
