Dude I knew from high school got sucker punched and knocked out by someone when he was arguing with another dude outside a bar. The original guy he was arguing with kicked him in the head and caved it in. The guy had to learn how to walk and talk again. He's mostly fine now from what I gather but I imagine he'll never be 100%. All over some dumb argument outside a bar. Petty street fighting and arguing are stupid. Save it for something worth dying for not some drunk dickhead.
