I cut my face by accident with a protractor in 4th year of high school once, I still have a slight slit scar that's kinda visible on left side of my mouth. It's not that serious but I barely bleed a lot anyways, but then again I do also have a lightning scar on my left hand from a cat scratch, I did also once fall on my butt, bled a slight bit from my left arm. But the most serious one has to be the slight hole in the exact centre of my chest....I don't wanna talk about how that got there....let's say it's triggering to most people to know.
