I'm a very open person, quite self critical and live and let live. No one like their flaws/ faults being pointed out but I take it on the chin and then consider if I want to change it. Same with criticisms/ comments on my life generally.
My mum is the exact opposite. She's never wrong, has no flaws, everything she does is beyond question.
For example, in the last five years I have, expressed concerns that my brother has a speech impediment (he does, school wanted to refer to salt but she refused), expressed concerns that my gran may have Alzheimer's - I work with dementia patients as does my mum (though in different capacities), I visited with my partner of 8 years who she'd seen at least twice a year and she couldn't remember his name, she also demonstrated other signs of aphasia and was unusually rude. My mum told me I was wrong, my grandma's memory was "exceptional" for her age. 2 Years later she was diagnosed with Alzheimer's. Last year she had a leak, all fixed but her house continued to smell damp - I mentioned this to her and she told me I was wrong, it didn't smell. Earlier this year my mum came to visit and told me my hall smelled of cat. I immediately got the cleaner out and sprayed/ wiped/ hoovered and mopped. I thanked her for her honesty, I'd rather know than not.
Earlier this year mum got a puppy. When I visited I mentioned the puppy wee smell. Was told I was wrong, it didn't smell, the puppy never toiletted in the house (bloody good puppy!).
It isn't as though she's defensive at the time and then does something about it- my brother still has a speech impediment 5 years later and the house smells worse than ever.
Obviously she doesn't want to know but I feel bad not saying anything. My siblings agree but know better than to mention it after the reaction I got!
Why does she have to be like this? Are some people just like this?
She has always been like this, it's one of the reasons my dad and she split and remember similar things from childhood.
There's also loads of other examples.
I'm not overly critical of her it's one thing a year max. She criticizes me every visit. Some warranted, others not.
