One older dickhead twice my age, I was 20 at the time, he used to nag and bitch about me not working the same amount of work as him, he went on for a week and everyone started seeing me as the lazy guy.
It was a bullshit, I worked same as everyone else but he being a fucking tryhard and me being shortest and youngest made me an easy target. He was one of the guys who have to argue and bitch to feed his self pity.
I finally snapped and told him that I will beat him up if he doesn't leave me alone. Next week he was muttering to himself and everyone considered me rude and angry. At least he left me alone.
