I'm not ruminating, really. I'm grateful she didn't call back. If she's still drinking, then she probably forgot I ever called. Or she figures one of the kids did it. Doesn't really matter. She hasn't tried to contact me and her number is still blocked. If my grandmother asks again, I'll tell her that I tried, but I also know how AM's been treating my sister, so I would hope she could respect my desire to not be asked to contact her again.
My sister and I couldn't be any more different and don't even really like each other, but she doesn't deserve to be called and cursed at. For the first time in her life she's actually happy. She deserves that.
