So I'm living with five others temporarily while I settle into a new job in a new city. It's 4 men and 1 other woman, the guys are all super nice but the woman (I'll call her A) is one of the most highly strung people I've ever met. She's passive aggressive, rude and very very sensitive. We're lucky that everyone who lives here is neat and considerate but naturally sometimes someone leaves a plate out for a couple of hours before washing up, or doesn't empty the bin the minute it's full. I'd say overall chores are shared equally (if anyone me and one of the men do a bit more) and we're lucky enough to have a weekly cleaner so it never gets that bad.
For a while we've all put up with the occasional tantrum from her, she's a bit younger and I think has quite an odd family (very demanding and entitled) and when she's happy she's good fun to live with. However last night she came in after a few drinks and absolutely lost it at the fact one of our housemates had left three boxes in a shared area. Because he moves out TOMORROW. We have a lot of space and it wasn't even close to being in the way.
He handled it pretty well but she was screaming at him for a good 30 minutes and ended up calling him a cunt and storming off. She's since been texting me and clearly thinks she's totally in the right but I feel like something has finally snapped in me. I don't want to get involved but feel she's already involved us all by being such a nightmare to live with. Am I being a pushover or is it best to keep the peace?
