There are people in this world who thrive on drama - we all know a few and we do our best to avoid them wherever possible. I've written a post a while back on people I refer to as Light Suckers - they just suck the joy and light from every encounter - their lives lurch from one crisis to the next and they almost seem to prefer it that way.
Cats are excellent avoiders of drama - if things are getting loud or over-heated, they make a quiet and stately exit from the area and find themselves a nice quiet cubbyhole to bunker down in until the dramatics have run out of fuel. Noise, shouting, crying and general hubbub are not their forte and they are happy to absent themselves from it.
I'm learning (in my midlife wisdom) there are certain people you just can't help. They are always going to be upset, or angry, or miserable, over something. If one thing is resolved then they will move on to the next crisis. Trying to bolster them or help them find solutions is a thankless and often pointless exercise. Investing yourself in their drama drags you down and starts to colour your world too.
So, read the chapter in the cat manual on ignoring bad behaviour - in there I'm sure you'll find mention of finding a quiet spot and waiting for the chaos to pass by before you come out to investigate the situation. I think they might be on to a good thing - being part of other people's dramas is not healthy or helpful - so practice avoidance wherever possible.
