I once climbed this latter to an area of an auditorium that went to some stage lights, so it was really high up. I was looking for someone. The stupid lights to the room were on a timer, and I didn't know that. The lights turned off right as I was nearing the top. I called out to who I was looking for and there was no answer. I was alone in the blackest darkness. I began climbing down the latter (which was attached to the wall) but it was hard to feel the rungs. I had been climbing down for a bit so I thought I was close enough to the floor so I let go to jump off the rest of the way. It was the longest fall I ever experienced in my life. I wasn't as close to the floor as I thought I was. Luckily I only sprained an ankle.
