My fmil is well tough to please. Everything is wrong unless it is her way. Well she has not helped with a single wedding plan (which is fine with me) nor have I asked her for help. She doesn't even talk about the wedding and if it is by chance brought up in front of her she changed the subject. She has already in the beginning of the planning process given us the I will not go if x y and z are invited. We did honor her request to keep the peace. Now out of no where she wants to do the seating chart for the reception she claims it is the mog's job. But I have never ever heard that and honestly I don't want her to do it. I want to do it myself. I have said nothing to her in regards to her request but avoiding it forever is not going to happen. Am I in the wrong is that something a mog typically does?
