When I was around the age of 3, I tried to wake my dad up by sitting on his back and pretending I was a horse. Because of how horrifically early it was he turned over, I flew off then proceeded to head but one of the old metal bicycle and cut open my eyebrow. I still have the scar which you can faintly see.

I get reminded of it at some family meals as how I was playing 'horsy' and my father gets a guilt trip.
