DH and I decided not to fly home to see our families over the holidays because it was too expensive and hard to see everyone (our families do not live near each other). My parents then suggested that they and my grandparents would come to my grandparents condo (which is 4 hours away from us) instead. We thought that was a great idea at the time, but recently Dh has been bummed about not getting to see his family for a very long time and suggested inviting his 14 yr old sister to come for the holidays.
DH thought is that he gets 1.5 weeks off over Christmas and his sister also has a break at this time. Sister is bummed about Christmas at home this yr because DH is gone, and their grandparents also are not around this year. In addition, they had to sell their house and now live in a tiny apt. If sister comes when she has another break, DH won't be able to take time off bc he needs to save his other time for when we are going to Europe in June with my parents.
We didn't work any details or even ask his sister yet, but I mentioned this to my mother the other day and she got really upset. She said some very negative things about DH's sister and his family always inviting themselves everywhere, even though I told her no one had even been asked yet. We talked again today and she was so mad at me for even suggesting to have his sister coming. I said we could just have Christmas at our house and she got even more mad. She said her and my grandparents are going to the condo and if we can come, then great if not, she didn't care.
The thing is, I'm not really sure where this is all coming from. The whole reason my family is even coming to our state is because they wanted to spend Christmas with us. They decided to go to the condo because it is more of a vacation spot then where we live and we really had no reason to be where we live. I also know that my dad and grandparents would be willing to either have sil come to the condo as well or have christmas at our house so that we can all be together.
I guess I just need help seeing her side of this and why she is so angry. I get that it's not ideal to change any plans right now, but really no plans have been made, nothing booked, no dates even set. And sister hasn't been asked or we don't even know if she will be able to come.
