Writing here because I have never known anyone to do this before so have no idea how to deal with it, I wouldn't say its a new thing but it is getting worse and more frequent and being honest its pissing me off.
Was in a shop with my mum, We were on opposite ends of the shop, Mum asked guy working there if he had something in stock so he went into the back to look, mum went to look at a display of items and ended up knocking the entire thing to the ground, Guy comes back out to see what happened and as soon as she saw him she said (made up name referring to me..) "Amy!! Why did you do that?" Basically making out it was me that did it..
In Tesco using self service, She ends up putting cash into where the card goes and someone had to come to open up the machine to get it out.. When he arrived.. "Amy, Why did you LET ME DO THAT" I was on the next machine over from her but still I got the blame in some way.
Cleaning her kitchen recently and I just happened to be at her house, She dropped a plant pot which smashed, I was upstairs doing something else and I heard her say from downstairs 'Oh ffs I just dropped this now with you fucking rushing me Amy' I hadn't said a word to her..
Also adding this which isn't me being blamed for something she did but is also something she is doing a lot lately..
Sat in her car, She was driving and I was in the back, I got a message from mums sister saying 'Tell your mum the thing she ordered from eBay arrived, hope you are well' I read the message out to mum and her reply was 'You know, You can be a right manipulative bitch sometimes you' I ended up getting out of the car and walking home as she wouldn't give me a good reason why she said that to me. I got called a manipulative bitch for reading a text out to her..
I have loads of examples but gave the above because the rest are just variants of the above, Basically she messes up or does something wrong and I either get 'why did you do that' or 'why did you let me do that' or 'I wouldn't have done that if you hadn't done xyz'
Best way to deal with it when it happens? If I try to defend myself in any way I then get 'Stop it with the woe is me bullshit'
