she had dementia. It got REAL bad toward the end. She would get angry with him and his mom. Lash out at them, curse at them. His mom didn't want to put her in a home because she felt it was HER duty to take care of her. I'd known her since the 1st grade. One of the sweetest people I've ever known...treated me like I was her grandson. Dementia took her down SO quickly. I dunno, man. Shit is tough. I wouldn't wish that on anyone.
