One of these days, he will pick a fight with the wrong person. Hopefully.
Karma. If you believe in that. It happens more than not.
I got sucker punched in HS by a jerk. I was planning to catch up to him in short order and lay him out the same way. A few days later he left a bar, drunk, and had a fender bender with someone who pulled across a the steer after the impact. He ran across the streets swings his fists like he was going to fight the other driver.....when he was run over by a truck. Dead. I did not mourn.
