Well I have some stories of things that happened to me that I think freak people out a little bit.
For instance, when I was 8 and cooking for myself in a small house where I lived alone (the main house was all of 150 ft away), I sliced my hand up pretty badly and stitched it back up without telling anyone. Well stitched isn't quite the right word. Held together is more accurate.
I was probably a bit more accident prone as a child than others and I think it confirms many people's worst fears. Personally, I think a few scars here and there add character and I'll still stitch myself up when I get hurt.
