We were strangers in the 27th row on a flight from Seattle. We didn't even exchange hellos.
You seemed queasy and kept putting your head on the seat in front of you. I was high on cold medication and decided you needed a back scratch.
We both realized what was happening, but it was too late.
I scratched your back in an affectionate manner for at least five seconds, and no more than ten.
I patted your back awkwardly at the conclusion of my back scratch and then pretended to be asleep.
If you're reading this, I'm sorry.
