Hi all.
I am 26 and my sister is 25.
I live with my parents and she doesn’t. My parents have gone on holiday this week and her and her boyfriend have come back to the house to stay. They are staying in my parents room.
I came home yesterday to him sitting in the kitchen topless and her walking around in a short top and lace thong knickers. My 21 year old brother was there too. I made a jokey comment about her covering up as I didn’t feel it was appropriate with myself and my brother in the house too.
This morning I was in my room (next to my parents room) on my knees and looking through my wardrobe. She strolls in with a short top and completely nothing on the bottom and starts a casual conversation with me about what we are having for dinner.
I asked her again, more seriously, this time to put something on. I explained to her that I don’t care what she decides to do behind closed doors, but because she has moved in for the week to my parents house that myself and my brother also have to live in, it isn’t appropriate.
She completely blew up on me and told me I was the one being unreasonable and that I’ve really upset her.
Am I being unreasonable? It just makes me feel very awkward and uncomfortable and I’ve spoken to my brother who has also said the same.
