Protracted Fighting
We were probably both around the age of ten. We were inseparable. If he wasn’t sleeping over at my house, I was sleeping over at his. One night we were in his bedroom looking for anything to do besides sleep and we both decided it would be fun to chuck things at each other in the dark.
We did this until we ran out of things to throw at eachother and then we would turn on the lights and survey what was thrown and for any signs of damage. Not an inch from my head, stuck solidly into the wall behind where I was sitting, was a protractor.
My friend was more concerned with the damage to the wall than how close he came to hitting me with it. I remember this fondly, many decades later. Story credit: Reddit / jimothy_mcgulligan
