My mother didn't 'fib', she downright 'lied' about everything but had the audacity to call me a liar
The first thing I remember her lying about was the existence of the easter bunny, tooth fairy and santa.
After my dad left us, she lied and said that he'd gone because he didn't love 'me' and never wanted to see me again. It turned out that she was blocking his access.
She told me that the man she was seeing when I was 14 was a 'lovely guy' and that he was moving in with us. He turned out to be a raging paedophile who regularly practiced his proclivity on me for the following 4½years. To this day (almost 40 years later) she still doesn't believe a word I've told her about what he did.
My son went to live with her when he was 10 (his choice, supported by socservs after we'd had tears of major issues with him which had serious effects on my disability. We later discovered that he was ND). She told him that his younger brother and I had been killed in a car crash because it's been driving whilst drunk. I've never driven with alcohol in my system, in fact, there are only 3 times in my life that I've had enough alcohol to have been considered over the driving limit, and want planning to go anywhere near my car keys, never mind my car on those occasions. She came unstuck a couple of years later when we bumped into him in his local town centre. She had to explain herself but never apologised for having lied!
Thankfully, I decided about 10 years ago to have no with her. I will know when she finale falls off her broomstick because my DSis still has contact, so I'll eventually be able to completely get her out of my head.
