It's all kicked off.
It's not my situation, but a friend's.
Her relationship with her mother is strained. Friend says it was emotionally neglectful and a stately homes situation. Nothing bad enough for social services, but nonetheless, unhappy.
Her mother is now retired and relies on friend a lot, and out of obligation, friend does what is asked of her. However, the mum is very passive aggressive, and does petty, spiteful things that she will then deny.
E.g. if friend is washing up, her mum will walk past and drop in a dirty, greasy spoon into the clean rinsing water, and plop a mug with a teabag into the washing up bowl.
Obviously it could easily be a mistake, but those kinds of mistakes only happen to Friend. Mum won't drop dirty dishes if golden child sister is washing up, and the tea bag will go into the bin.
The mum also has a habit, when company is over, of telling nasty stories about friend, couched as jokes. E.g. she was so fat she got stuck in a slide. Or 'Her hair was so 'unmanageable' that one year mum just cut it off and everyone they encountered thought friend was a boy! Hilarious!'
Over the decades, friend has learnt trying to talk about things with mum gets nowhere. Mum is the type who 'doesn't believe in therapy' and 'back in the day we just got on with it', etc.
So what friend does is just write things down in a little notebook to vent. E.g. Today mum got into a huff because I bought Tetley's tea bags instead of Yorkshire. I told her you asked for Tetley's. She denied it then I showed her the text that said Tetley's, now I'm getting the silent treatment.
Well, on Sunday Friend's mum found the book. She was looking for a stapler and found the notebook in friends work from home desk drawer. Friend does not know how much she read, but mum was saying: 'If I'm that much of a burden I'll just go to Dignitas' and it's clear friend has no love for her mother, because if you love someone you don't make a list of how they annoyed you, quoting the bible 'love keeps no record of wrongs'
In this situation, who (if anyone) is in the wrong?
