Maybe you just wait a minute until her legs get tired and everyone has had a chance to cool off and then talk about it? Maybe you have everyone leave the room for a minute? Maybe this student isn't going to be acting like this when no one is around to see it. I get it, no one has any minutes to wait, everything must happen now or it's ruined. But then when you look back on it everyone in this situation is going to be like, "crap, this could have turned out differently with a little patience."
It's one of my main problems with law enforcement. No patience. They don't like it when they aren't on the front foot at all times. They aren't able to properly recover from not being on the front foot at all times and act out violently immediately. They aren't able to outsmart anyone, only out-intimadate them (sometimes lol).
