i don't enjoy watching things like that, necessarily, but what can you do? as a former lifeguard, i'm genuinely scared for him and i'm sure that punch put him in a hospital bed. it was gruesome, savage, and unnecessary and i pray the kid's alright. at the same time, i don't know literally any of those people nor can i do anything about it.
Wow what a tough guy beating up a kid who can hardly stand up and is half your size. Sure it was provoked but have some sense and don't put your ego in front of everything. Try to locate the kids friends and get them to deal with him or something.
Although I did lol when the girl screamed "I'M A NURSE" and pretty much told everyone to clear out and then bent over and we saw the thong shot.
