I have quite a few scars:
Behind my ear: From the cochlear implant operation
On both of my knee cap: Feel on a rock during bike ride, was pretty deep and nasty. The skin on the scar itself is too fucking smooth
Under both of my knee caps: Brother was stupid enough to put nails in the treehouse stair, I stepped on one but it didn't go in my foot. Sure enough, I realized what I had stepped on and quickly jumped onto the rough, wooden rail and afterward, he got a good whupping from my Dad
My foot: There was some werid skin thingy on my foot, so the doctor cut a huge section and it still haven't healed. It looks sunken.
My wrist: I seriously don't have a clue as to where that one came from, perhaps an accident when I was a baby.
