I can see how it looks like I got the shirt end of the stick. I probably should have requested to switch off or something. I actually have a different battle I'm fighting for Christmas this year. One a year is enough with this family so I don't always look like the bad guy making waves. They like easy going people that go along. I do that enough and am fairly easy going, but when something is important to me, I make my feelings known.
Anyway, I feel that MIL caters to SIL to the extent that we are expected to just fall in line. When she was here, she told me that she needed to reschedule Xmas eve be side SIL's child was singing In Church that evening. They would then be going to SIL's for pizza. So, she wanted to have Xmas eve on the 23rd or something. I mentioned that I was working that day, and so I probably couldn't come too early. (I'm the only I one that works in a non-school setting so everyone else is free.) so then she invited us to their church service. I don't want to ho to an event where inviting us has clearly been an afterthought by someone not even hosting. DH doesn't want to go either. So, they will want to reschedule our families' Xmas celebration. I'm cooking my turkey day dinner the weekend before Christmas so we have a bunch if days for leftovers. I'm not sure when the celebration will take place.
Sorry for the ramble.
