When I was two I was sitting on a tree stump and fire ants crawled up my legs leading themselves up to my hands. They ate through my skin causing small little indentions on my fingers and legs. Nothing to big but I've three small indention on my left hand ring finger and slightly bigger indention on my right leg. Pretty good work for a small set of fire ants if I do say so myself.
My memory isn't scared but my body sure is.
