So, maybe just forgive her for posting her status?
That was done before I posted.
I just, like you said, I wasn't sure how or if I should proceed. And I wasn't sure if I was being overly sensitive.
She's my niece and I love her. It's just, I guess, 'growing pains.' I suppose as we get more comfortable living with each other, it's bound to happen.
Oh and to answer a PP....'yes' we did sit down with her and tell her the basic rules of what was expected. Most of the 'rules' are not an issue but there are a couple where...we are still going back and forth.
I also think over the summer, since youngestson and I were not on our typical schedule, the rules got relaxed and now that we are getting ready to get back on track, there's some push-back.
I'm sure she liked it during summer...having the entire room to herself but she knew that coming to live with us meant that she had to share. Besides, like DH said "whatever we give her will be 100x's better than what my sister can give her." In other words, she didn't even have a room with her mom and here, at least, she gets a room, even if during the day, she has to share. (she's at school during the day so it's really not an issue and yet, I get the feeling that she has become 'territorial' with youngestson's school room so I think we will have to address that eventually)
