I saw a similar incident when I was a young teen . 18 year old tough guy was harassing a senior citizen . I was too small to stick up for the old guy but was surprised to hear the old man tell the tough guy he should keep his big mouth shut . The tough guy moved towards the old man and I got ready to scream help when suddenly the old guy flashes out an upper cut that caught tough guy right on the button . The only thing holding tough guy up was the wall he fell against. He was totally dazed when he fell against the wall and as his legs buckled he fell forward . Bam . The old guy nailed him again , right on the button , hard . I'm in shock cause now I think fuck he's gonna kill the young shit thead , No expression on the old man's face as he stepped in to tag the poor fucker as he came off the wall again. Bam . Lights fucking out.
Tough guy was no pussy but he got fucked up that day . I'm in shock trying to figure out what the hell just happened when an older guy comes over and gives the senior citizen shit for beating the fuck out of tough guy . That's when I learned the old guy was an ex prize fighter . The prize fighter mumbled something about having warned the bully to leave him alone and walked away . That is the day I learned to never under estimate your opponent cause it's really painful when you are wrong.
