I was cutting a carrot when I was 12 or 13 I think, and I tried to take off half the tip of my finger, but failed and only managed to get it to bleed nonstop fora while.

Also when I was 5 and in kindergarten, my dad came to pick me up from daycare on day, and I ran to go get my stuff and ran into a bookshelf thing and busted my chin open, it was bloody, and had to get stitches that night.
