I don't have many scars, fortunately. The weirdest one I have is one in the left side of my right knee. It's like 2.5cm long and 1cm wide in the center, because I didn't get stitches and it didn't heal properly, and it kind of looks like an eye.
And I got it doing stupid shit as a kid: I climbed a street light and on my way down afterwards I got cut by a metal thingy holding a paper bin that wasn't properly cut and folded after they installed it (I know this probably sounds weird and maybe you don't understand what I mean, but I really don't know how to explain it better ^^")
