When I was ~10 I was running around the house with a white bedsheet over my head. I was pretending to be a ghost while I chased my older brother around the house. Unfortunately I slipped backwards on the sheet and hit the back of my head on my mom's solid oak coffee table. Immediately blood started soaking the sheet red and I obviously screamed out in pain. My mom came running into the living room to find me screaming and the sheet just turning more and more red.

At this time we lived about an hour away from the nearest hospital and my mom knew if she tried to take me in for stitches that I would probably bite the doctor or something (I have a pathological fear of needles). So she opted to shave my head and tape it shut. Then she instructed my brother to keep me awake for the next few hours (she was worried about a concussion) and she let me watch whatever movie or play whatever video game I wanted for the rest of the day.

It healed fine and now I have a small scar on the back of my head that is only visible if I shave my hair super short.
