In my houseshare, there is a running joke about someone always leaving a mess in the kitchen but nobody admitting to it. Every single person denies it's them but obviously it is one of us. It's only one person making a mess.
Yesterday when it was just me and this other person at home they made a mess and left it and I joked afterwards to them that I had finally found the culprit. I was laughing when saying this and obviously joking. I don't really care about the mess or who makes it, it's kinda frustrating but not a big deal. However, they went ballistic at me.
They started shouting saying how they had to leave the mess as they had an important call to take and it wasn't even their mess completely as housemates had also made a mess before and left x, y and z on the kitchen all whilst swearing and ranting. I just said "I was just joking, it's fine, it's ok, it's no big deal, etc" they then went and called all of our housemates to get proof that certain things left on the side in the kitchen weren't them.
That was yesterday and today they are still bringing it up and completely angry over it. They won't talk to me. Door slamming, ranting about it. Saying I'm making them out to be a liar and accusing them of something they didn't do, etc. I keep saying I was joking.
WIBU and AIBU? I regret saying it but at the same time I think this response is completely over-the-top.
