Had a few knives pulled on me. Favorite was a drunk acquaintance yelling at a black dude that almost hit us in a Mercedes with tinted windows... Car stopped very quickly and the door opened, haha. Drunk guy never even saw it even though it was enormous. I was fully prepared to let him die as I ran but I guess the guy realized he was dealing with a moron and just left.
The scar on my face is not an exciting story. When I was young and poorish I used to live in Roxbury, which is the poor black shithole neighborhood of Boston. I didn't know it when I moved there but there is a particular street that if you walk down, you get jumped by a bunch of dicks. I actually don't remember any weapon in that case, don't remember getting hit with anything. Dealt with the first few attackers and then ran away, only to notice I was COVERED in blood. I suspect it was some sort of club/liquor bottle due to the jagged nature of the cut, but I dunno.
