I’m convinced my grandma fell on purpose

So for a little context, at the beginning of the year, my mom fell and broke her foot. She did this by wearing crocs, they got stuck on our hardwood floor and they turned on her so she fell. That was in January and she’s still in a boot now. That’ll be relevant in a bit. About two weeks ago we went out of town to visit some family. Every time we go out of town, my dad’s mom, my grandma, watches our little dogs. He told her that we would be gone from Friday night to Sunday night and would pick them up on Sunday. On Saturday night, we’re at my cousin’s place visiting with my mom’s side and grandma calls my dad. She FULLY chews him out and asks him when he’s going to be there to pick up the dogs and all that jazz but really makes sure to talk to him like he’s shit. Here’s the best part, she’s clearly drunk. And no, she doesn’t have any memory issues or anything like that, she just has a mean streak. My dad gets off the phone and he now feels like he did something wrong when she was clearly just being an asshole (this isn’t the first time she’s behaved like this). It shifted the mood of the weekend completely. We go to pick up the dogs the next day, she doesn’t apologize and just pretends like nothing happened. I’m peeved because I hate seeing my dad be made to feel like he fucked up when all it is is his mom being an old crotchety drunk. Fast forward to last week. My dad gets a call from grandma and she’s fallen and he has to go over there and help her up because she couldn’t get up herself. Mind you, she wears a life alert necklace and for some reason never uses it when necessary. This isn’t the first time that she’s fallen and couldn’t get up, one time she allegedly had been on the ground for two days. Another time she laid in bed for 3 days, pissed and shit on herself but still had fresh ice water by her bed when my dad got there AND CLEANED UP HER PISS AND SHIT and then went on to make our lives hell for 4 months but that was a whole other thing. I just chalked it up to her being old until I asked my dad yesterday what happened. Her and my mom DO NOT get along but it’s understandable because she’s the definition of a needy, arrogant boomer. She fell the EXACT SAME WAY MY MOM DID. Wearing crocs, was walking, croc got stuck, and she fell. Respectfully, I call bullshit. You act like an asshole and then you magically fall the exact same way my mom did not even a week later? Come on dude. Absolutely not. AND you have a history of doing weird shit for attention? I’m not buying it.
