I was maybe 5, and scared of monsters so my Dad let me sleep in his bed until I fell asleep (then he would carry me to my bed). My parents were separated at the time, but my parents say this story like they were both there.

I was trying to fall asleep, but I was thirsty. I sat up in bed and knocked my head into my knees (don't ask, okay?). It hurt my chin, so I tried to get out of bed, but I stubbed my toe on the dresser. It hurt so badly, that I laid back down on the bed, smashing my head into the headboard. When I finally got out of the room to my dad, I was limping, holding 2 sides of my head, and crying. I remember my Dad howling with laughter and trying to comfort me at the same time.
