i live in a apartment complex around half an hour out of the city, i live on the first floor but i'm above the entrance to the car-park so my house is maybe 5 metres up? 

i had a friend over and we were playing a game were he would throw these mini balls through my open window and i would catch them as they came. 
he threw a red one directly up so i would have to catch in out the window, i jump on my bed, leaning to catch and promptly trip, shifting my balance and making me slip out the window, do a back flip and fall on a fresh garden bed on my back, apart from a few grazes i was fine but we didn't end up playing that again.

TIFU by falling out my apartment window.
