I have one on the forehead. I got that when I was six: I fell while running in my aunt's balcony and I hit the marble with my head. It wasn't cool at all, but I suppose I didn't die *checks*
Like beserker, I have one on my eyebrow. I was hit by a wardrobe's falling door when I was 8 (I remember my mother started crying seeing all the blood covering my face because she thought it was the eye, not the eyebrow, and istead of trying to figure out if it really was the eye or not I kept on shouting at her "I'm sorry!"). It happened in the middle of the night (these things always happen at impossible hours) and it was hard to find a doctor for getting stitches etc. I knew it was going to happen. That door was broken, but nobody wanted to repair it and that was the result
I have three scars on my knee caused by surgery. Wasted time. Surgery couldn't fix the knee's problem and I got these scars for nothing.
Other than that, I have more than I can remeber at the moment, I have tons, mainly little scars and burns on shoulders, arms, hands and legs. Their stories aren't very interesting for the occasional reader, and I wouldn't like to talk about them in front of strangers anyway .
