I made a rope and climbing harness out of dog leashes. I strapped it to my chimney and tried to repel down it. About half way down and a story from the concrete below my hand got tangled and stuck. I could either let go or dangle there for hours till my mom got home. I decided to let go. I landed with one foot on the ground and one on the boombox below that had been blasting my tunes. I rolled my ankle very badly and had to crawl back into the house. I watched cartoons until my mom got home. When she got home she asked why I looked strange. I told her "My ankle hurts like a bitch because I fell off the roof." I'm not sure if she slapped me because I cussed or because I could have died.
