Don't be upset my ass!

My dad specifically said he didn't want Cindy's kids living in his home after he passed.

The first thing she did when she came back to Vancouver was to tell her son to move into my dad's place and she brought her daughter, too. It's fine that she wants the support of her children in her time of grief, but 1. Her son had his own place and could have had his sister stay there. 2. Cindy has her own place, and her tenant already moved out.

First, she was all gung ho about buying my dad's place, and when I brought up that my dad didn't want anyone sharing his home, she said this was only temporary, meaning that eventually, his condo would be hers anyway and that her kids would only be disrespecting my father's wishes for a few months.

Well, her daughter has decided to be "helpful" in clearing out her stuff...and my dad's stuff. I DO NOT like her dealing with any of my dad's belongings. 

I was all set to go get my Dad's Nintendo for my uncle when I go visit in a couple of weeks. I told Cindy that I was going to pick it up. She hasn't said that it's gone, but she apologized and told me that her daughter was only trying to be helpful and thought it was Cindy's. So it sounds like my dad's Nintendo is gone. 

It also sounds like she is reconsidering purchasing my dad's place and is taking him up on his offer to live in it rent-free.

Do I still have to play nice? Right now, I'd really like her to move out or buy my dad's place. And I hope to never have to deal with her again. I also feel like I'm letting down my dad somehow.
