My mom spoke to my grandpa yesterday and told him about my grandma's latest shenanigans. He threw up his hands, took the Lord's name a few times, and told her that 1) Grandma was never upset, and certainly wasn't up crying all night. 2) Uncle wasn't upset because uncle has no short-term memory and didn't care anyway. And 3) that he overheard my grandma telling my uncle, "Well, now you know where you stand on their [my immediate family's] pecking order: AT THE BOTTOM!" It didn't occur to my grandpa what she meant, but it made sense when he heard the schit she was pulling.
My grandma is a rotten piece of schit. Sadly, she'll never change. She'll never treat any of us (including her own children) with any ounce of respect. I hope her bladder falls out for good and takes all her other essential organs with it.
Re: Speaking of evil grandmas
You can't change her and it's good you know that.
All you can do is not get worked up or be surprised about her crappy attitude.
