From what I have been told my MIL wasn't the nicest person to begin with. She has always talked nasty, it would shock me. I am not a prude but it would get bad sometimes. I wouldn't go over to her house that often because of how she acted. I really think this started years and years ago. This has taught me one thing, and I have someone checking on it today. Make sure I have nursing home insurance, I don't want to have to put my kids through any of this. If this was to happen to me.
