I came off a roof years ago. Thanks to a snow bank I didn’t get hurt. I haven’t got on a ladder since then except DD’s 3 step one.
I had a ladder slide down the side of my 2 story house and land on a concrete driveway...with me on it. I was boarding up the upstairs windows in preparation for a hurricane, with the help of a neighbor. I ended up dislocating my big toe, cut the inside of my lower lip, and chipping a front tooth. To make matters worse, the hurricane veered south, so I didn't need to bother with boarding up. I haven't been on anything bigger than a step ladder ever since.
