Okay so my parents and FI's parents are splitting the cost of the rehearsal dinner.However, FI's parents have taken it upon themselves to pick the menu and creating a seating chart for the RD without talking to my parents. The menu didn't really bother anyone. But in the seating chart, FI's parents have sat themselves with my parents. As you recall, with my mom's dislike for FI's parents + recent hospitalization for bipoloar disorder, I specifically sat them apart at the wedding. Well, FI's parents think that was inappropriate, as the parents are "supposed to" sit together at the wedding. So now they have corrected our "mistake" by seating them together at the RD. FI doesn't want to say anything to his parents because he thinks it will be awkward (ie. it will become obvious that we're trying to keep them apart). Is there some way we can get them to not sit together? I suggested telling FIL's that my parents would like to be seated with their out of town guests, or having my parents call FIL's and say that directly. FI thinks that will still seem "shady." Sorry for all the quotes. And TIA.
