My tendency to scar:
I have multiple from chicken pox.
One from a door, I scraped my arm on a metal door on a ferry.
A tv remote. I am not joking. I had superglue in that, hit me in between my eyes.
A scar from a box jellyfish, which wasn't bad (medically) it just hurt a hell of a lot. I got stung by a lionsmane and that didn't scar though.
...or just paranoid?
