When I was around 8, a neighborhood kid was swinging around a light pole, just a plain metal pole but it had the wirenut box attached to the side about a foot from the ground, which he was standing on while spinning.
His foot slipped, the corner of this box ripped his ankle open, cut right up from the top of the shoe about 6 inches into his lower calf/ankle.
He screamed and ran home, blood pouring everywhere. Saw him a few days later with massive stitches and bruising all over his leg. Wasn’t as bad as it looked, but fuck me it still makes me wince thinking of my ankle being sliced by a dull metal corner by weight and gravity alone.
I encountered a very aggressive stray dog when I was about 14. It bolted after me, I climbed and vaulted over a chain link fence to get away. When I landed on the other side I thought I caught my sleeve on the top of the fence. Nope. At the top, one of the links was bent outward into a hook shape. It entered my wrist and exited my palm. Adrenaline is a hell of a drug because I barely felt it. Probably should have gone to the hospital but my dumb ass just rinsed it off when I got home and put a bandaid on it. Now I have a long scar running down my wrist where it entered and ripped. A small exit hole near my palm.
