*Dropping the comfort bar on a passing chair, resulting in the people who were about to sit in said chair to get bowled over into the pit.

I’m guessing this was a grown adult? I volunteer at my kids’ school and I’ve seen some extremely impulsive behavior from eight year olds where they clearly didn’t think about what would happen if they pulled some stunt that popped into their heads. Dropping the comfort bar sounds like that kind of thing. No thought about who it might affect; just hey, that’s something to do. It’s not even something cool, it’s just something. Like WTF???
