Thanksgiving fiasco all over again!

Here we go again with what to do for Thanksgiving. I have posted the past couple of years about the problems with the other sis-in-law and her games and this year is no exception to the rule. I put the email call out yesterday as I usually do for turkey day at our house as usual for the past umpteen years but my email is pretty silent this weekend. I did get a call from the niece and nephew (the nephew is The Hubby's bros son), anyway she said the SIL informed her that they would be doing T-day at their home at the lake for Her children and that they would be welcome if they didn't have any other plans. Hey wait a minute, now aren't your husbands kids, your step-children a part of your family that should automatically be included in the plans for the turkey feast. She is so excluding any part of the family, our family and trying to make a whole new family for herself. It has been very evident for awhile that she is stirring up some trouble. Recently she made my MIL cry and I will not have that. I don't think the BIL-her hubby knows her shenanigans and I would love for him to find out. She has now started going after the MIL saying to the same previously mentioned niece that the MIL doesn't believe in God and talking bad about her to the niece, again behind the husbands back, when he leaves a room. How sneaky is that to go after your husbands mother, 81 year old mother to the grown grandchildren. I may have to get into the middle little miss smarty pants and cause a stir.
