We are visiting some family members in a couple of weekends. They have talked about us all joining them in church on the Sunday morning. I don't want to go, I understand they want to go, and I'm happy for my children and partner to attend if they want to but I don't want to. But... I am a guest staying in their house over the weekend, so don't want to be mega rude either.
Is there a debretts guide for this sort of thing, or should I stick to my guns? It is going to be a mega stressful weekend anyway as we really don't see each other very often and have very little in common, and I know I will end up having to counsel DP for days afterwards as the relationship between him and the family is vexed.
