I was a non functioning alcoholic and ran with some rough types in my late teens/early 20s and have both kicked ass and had my ass kicked. Mostly drunken barfights.
One time someone legitimately mistook me for someone else and started cussing at me, so I started cussing back and pushed him to the ground. He got up and did a really neat move actually where he faked a kick and then socked me right in the cheek, knocked me on my ass. I apologized, got up, we figured out the misunderstanding and he bought me a beer.
You, uh… you ok bro?
I was maybe a little inebriated, and he was very rude.
He had to wait for the next train, and I had a sore jaw for a week. Mild inconveniences al round. I think everyone got what they deserved.
