I remember one time I was somewhere with my family, I think we were at my friends house, I was on a bunkbed trying too get down and my sister was in the room.
I managed too somewhat get down but I misinterpreted how far the floor was so when I jump-climbed down, I slammed onto the floor.
It didn't hurt [Because of adrenaline] but we did that silent laugh thing you do at sleepovers.
