Partner arranged to go out. I expected it to be a boozy/late night and was quite happy to have a quiet night in by myself. Around midnight I was downstairs just getting ready to go to bed when they came home along with a friend who also happens to be an acquaintance of mine (not someone I know well - think dad you say hello to at the school gates sort of thing). I'm sitting here in my nightie and slippers with a conditioning treatment on my hair looking a bit like that girl out of The Ring. I'm happy to host people/have people to the house etc. but I'm just not comfortable having someone come into my space unannounced like that so I sort of avoided saying hi and sneaked away to bed. I am also in a bad mood because I couldn't get to sleep until said person left (our house is very small so you can hear conversations, see landing/bathroom lights going on and off, dogs also won't settle until they've gone home etc). My partner also made it worse by coming into the bedroom at 2am while I'm trying to get to sleep to ask me if I wanted to share their takeaway. No, I just want to be left in peace! They think I am being unreasonable, it's their home too and they shouldn't have to 'placate me'. I think they are being unreasonable and a heads up in advance would have been good so I could have at least known to get myself out the way.
