Input: Text: i was inspired by u/hdalby33 and the story of the binoculars, so i will say this was a childhood story of mine too, not actually today. i was about 6 years old and very clumsy. my father, a proud u.s. marine, had a very heavy ceramic coin bank that was shaped and painted in the resemblance of a marine corps mascot bulldog. this bank was about 2 feet tall and weighed about 20 pounds. one day, i was running obnoxiously around the house, horseplaying. my mother warned me to quit, but like a stubborn 6-year-old, i ignored the warning and continued my general jackassery. while running down the carpeted hallway, i tripped on my own damn large feet and flew head-first into the coin bank. i saw nothing but black for a few seconds, and the intense pain in my forehead stopped my nonsense immediately. cue howling and crying from me, and my mother coming to make sure i hadn't seriously injured myself, followed by a "i told you to quit". i am now 29 years old. to this day, i have a hard knot on my forehead, right above my right eyebrow that has never gone away. it can still be felt easily, and there is an obvious tangible difference in the two sides of my forehead. lesson learned the hard way.

TIFU by hitting my head so hard I have a permanent goose-egg
