My sister in law. She is stepmother to my 13 year old niece, and mom to my 7 year old niece. Every year, her "birthday parties" for these girls consists of her inviting us over with 2 days notice for pizza and ice cream cake. She always says to be there at 5:30, and usually changes it to 6:00. They are always already eating when we get there. And, inevitably, the 13 year old has to be at dance by 7:30....so, yeah, we feel real welcome. Well, she texts Tuesday to tell us to come over Thursday. DH had court at 6:00, then plans to head up to a hockey game. I was going to take DS, but he was kinda sick, so I cancelled. Well, she flipped out and got all bitchy that DH went to the hockey game and that no one came. Keep in mind, my MIL asked her why we couldn't just do it Sunday, so everyone could come, and she said no, we can't. Turns out, they are doing cake with her family on Sunday. Our whole family is like an extra 6 people. To top it all off, they wanted to take DS shopping with them tomorrow, and I really didn't want them to. I like my quiet weekend home with my baby. They never bother to come see him, and every few weeks they just expect us to let them take him for hours on end. Their house is fucking chaotic, and I never get to see my nieces. Whew! Sorry that was so long. And my paragraphs never show up on the iPad, so I apologize for the wall o'text.

Re: Vent tl;dr
In Laws.
nuff said.
All of that sounds really frustrating. My in laws also complain constantly that they never see DS but they never make an effort to do so. We always cater to them.
