Well, she wasn't a friend, but she was my friend's roommate...
She got up on the top bunk bed, probably 7 feet off the floor, and one of her male friends was there. I was in the room helping my friend get dressed because we were going to go out dancing that night. Well, her roommate started wrestling with the guy, up on that narrow bunk with no rails, and eventually you know what happened. He threw her off the bunk.
Now, landing on the floor probably wouldn't have hurt her too badly... except that the bottom bunk wasn't directly underneath the top, rather sticking out at a ninety degree angle. But she didn't land on the bottom bunk, or at least not all of her landed on the bottom bunk. Her legs landed there... the rest of her body landed on the floor.
The place where all of that weight came to rest was her nose. I wasn't looking that way at the time, but everyone in the room heard the CRACK! when her nose broke. Luckily, she did not break her neck.
Instead of going dancing, several of our friends dragged her out to the car and took her to the emergency room, while I stayed with my friend, who was in complete shock. We spent the evening cleaning up the blood.
Up, up and away!
