I don't like to admit it, and I have never done this before, but if I wanted to I could pick someone's every insecurity to absolute pieces and I suppose this is what I'd do in such a situation, so hurt them emotionally I guess? I don't find it all that difficult to tell where people are insecure or sensitive or upset and I know that if I wanted to I could play on those aspects of someone very easily. It's something I do all I possibly can to avoid doing, and something (thankfully) that rarely even crosses my mind at all, but if I was definitely going to do something, then that'd be it. I wouldn't bother getting physical, breaking anything, or running away when I could so easily do so much more without touching a thing.
I take quite a lot of time thinking about people, how certain factors affect them, etc. so I'll generally have someone's insecurities identified by this point and all I have to do is a bit of quick thinking to bring them out in a heated moment. How exactly I'd do it would depend on who the person was, as what I'd say varies between people.
...yeah I sound like a right monster now, haha, but that's me at my worst I guess?
