I suppose everyone has "That" scar, what is it?
I guess mine would be a scar I have on the back of my hand from a kangaroo...

Edit: Now I think about there's a few.

One on the back of my leg from falling off my motorbike and burning it on the exhaust pipe.

When I sliced my finger open with a dog food can.

When my friend accidentally burnt me with a hot glue gun.

A mysterious one on my hand after a heavy night of being drunk.

Maybe not that interesting

A shard of glass embedded itself deep in my forehead in a car accident. It left behind an arrowhead-shaped scar.

I've only got one and it was from the angry little redheaded girl who went to my school. Scratched me in middle school while playing basketball.

Interesting in what way? I got tons of small to mid-size scars all over the place, mostly on my limbs and back.

I have a scar between the middle finger and the ring finger of my right hand from deflecting a knife someone threw at me. Just to the left of the webbing between them. There is a story there.

Got scars on both shins from sliding 60ft straight down a Coconut tree I climbed up when I was a sophomore in high school. Flayed my shins pretty good, although the scars are not all that noticeable now.

Have a small scar on the bridge of my nose slightly to the left of it just under the brow line. That was from a Kayak paddle. There is a story there as well.

Have a few small ones all over my back from smashing on reef while surfing. It happens.

Well...[censored]...now I am looking all over the place on my body and remembering where I acquired all these scars lol. Good times. At least I have avoided the disfiguring kind of scars.
