I sit here in a silent house, with a big glass of wine (or three), so happy that the invasion of the ILs is over. Beware, this is long and may not make much sense.Andy's birthday party on Saturday was really fun. We had a bunch of friends and family over and it was lovely.However, I am lucky that I didn't kick either my MIL or SIL in the shins at some point.I think my favorite part of the weekend was this:Saturday morning, my H, Andy and I were out running errands before the party that started at noon. We had our morning pretty mapped out. Because SIL never told us what her plan was, we did not figure her family's (including MIL) arrival into our plans.As we are in Target picking up some last minute things, MIL calls H's cell to say that SIL dropped off MIL, devil niece (which I will now call DN), and SIL's moose of a dog on our porch. SIL and BIL had errands to run, so they just left everybody sitting on our porch before they even knew where we were. It took my H and I at least a half an hour to get home from that point. While we continued to get ready for the party, my MIL sat down in front of her computer and zoned out paying zero attention to DN. DN ran around our house getting into everything she could. As I was getting Andy down for his nap, she kept running into his room and screaming his name at the top of her lungs. I calmly asked her to go out and find grandma, go play in the other room, etc, only to have her turn right back around and scream again.We ended up having DN running around like a screaming psycho for three hours before BIL and SIL showed up (this was an hour into the party).Throughout the day, I did not see my SIL interact with her daughter one time.After Andy was in bed for the evening, and I had told DN to stop whatever she was doing for the 80 billionth time, SIL comes into the family room and yells at DN, "If I have to tell you to stop one more time today..."You want to talk about parents shoving off their responsibility onto others, I've got some more.
