When I was about 6, I fell into a rose bush. I still have a scar about 3-4" long, and about 1/2" wide across my left calf. Later, my parents realized they probably should have taken me to the hospital for stitches, but at the time thought cleaning & bandaging was sufficient. Once the size of the scar became apparent, Mom asked my doctor about getting it removed, if ever I wanted that done, but really, I'm used to it now. No urge to get rid of it.
I also have a small scar on my right knee, from falling while running in gravel around that same age. Then a year after that, I fell in gravel again, and scraped off half the scar. :-) There's also an elbow scar from a skateboarding accident. I'm lucky I didn't have any scarring from the hot soup incident when I was 5...
It's amazing I never broke a bone as a kid. Well, I kinda did - I wrecked my bike (about the same age as the rosebush incident), and managed to knock out my front teeth as well as a chunk of my upper jaw. But that's the only broken bone to date.
