Don't try and scare me out of fighting by giving me little horrifying scenarios. I'm well aware of what can and will happen in a fight against someone more powerful than me.
I'm not a big guy because I like physical confrontation? What the hell?
I've gotten a bloody nose and got my cornea scratched up - had to be a pirate for a week or so.

Seriously though, I got thrown into the ground and pounced on by two kids from my school who wanted to be 'gangsters'. Real thugs.

So, I got bits of gravel/glass (back bump at school where people smoke and drink) in my eye. It's funny when you hear people say you don't really feel it until after the adrenaline dies - 'cause it hurt like hell when it happened to me.
Anyway, I've been in a handful of fights. Scuffles. Nothing life-threatening, no.
My dad has been abusive since I was young, and twice I pulled a knife on him out of defense after things got too serious. That was when I was 14-15. He's 6'2", Italian/German (as am I) and 240 lbs., roughly. So, he definitely could have smashed me to pieces. He was more than drunk enough. He'd hit my mom in the past, and hit me enough - I doubt he would've had an attack of conscience.
