Sister in law was once on the bluetooth speaker in my brother’s car. She didn’t realise I was in the car when my brother picked up her call. Out of nowhere she randomly refers to me using a swear word. I was absolutely shocked! My brother hung up immediately and tried to style it - “oh she’s misheard what I said”.
But to be honest I have never felt the same towards her after that incident. We had always been perfectly nice to each other when we met up. I am polite to a fault and she has good manners also (in public). In fact I had always gone out of my way to be nice - e.g. home cooked meals when I was heavily pregnant, dropping off baked goods when I made too much etc.
After I heard this a couple of years ago I kind of just detached emotionally. Still perfectly civil.
Am I being harsh? Would you have got over it?
I never got an apology and we never addressed it.
