A friend of mine recently had an accident with some kind of power saw. It jumped up and cut his cheek, and he had to get several stitches. It was a miracle that it didn't do more damage- get his eye or ear or something. He was left with a pretty decent scar.
I don't want to trivialise my friends' near miss, but, to be honest, I've always kind of wanted a cool scar. One that would make me look cooler and tougher than I look now. (Did you see what I did there? Not sure if I'm being big headed or self deprecating are you? That's how intricate the web that I weave is to the naked eye).
Back on topic, I wouldn't want the scar to be too drastic and disfiguring, just a cool nick here or there. Like I've been in a dangerous tussle and lived to tell the tale. But only just.
A prerequisite for a scar to be cool is that it can't be too symmetrical. I only have one decent scar, but it's silly looking and symmetrical, so it in no way qualifies as being cool. It's a shiny round circle on the back of my head. Very circular, very pink, very shiny, very symmetrical. According to legend, it occurred soon after I was born, when the nurses took me away to be weighed or something or other. Maybe they swung me by the legs and accidentally clipped a passing trolley doing the rounds or something. Hard to say. They denied any responsibility. But look at me now, nurses. LOOOK AT MEEEEEEE! Avert your eyes, children!
Because of it's perfectly formed symetricalityness, it doesn't even look much like a scar, let a lone a cool one. I once had someone mistake it for a USB port and try to plug in their thumb drive there. Another person treated it like a miniature pregnant belly and patted it, cooing, "Awwww" lovingly. Still a third person gave it a rub, before standing back waiting for a genie to come out.
