I had a recent thread running about having an abscess in my lip. Unfortunately I think it is going to scar.
It got me thinking about scars and the stories behind them.
I have a scar running across my arse cheek from sitting on my hair straighteners as a teen. That was fun when it went all scabby and stuck to my school tights. I have a small scar on my finger from slicing straight through a bagel, and a fag burn scar on my hand from my drunk friend (again as a teen). I also have the obligatory pregnancy stretch marks that still resemble a british road map 6 years on 
So, what scars do you have and what are the stories behind them?
