We have an impending visit to their house for several days. They have two guest rooms, so me and DH go in one, our two children in the other.
Unfortunately MIL and FIL have had a serious falling out for several months now - basically because FIL is an argumentative grumpy old sod and MIL is finally losing patience with him, and it appears they no longer share a bed. The last time we visited, I came downstairs in the morning (our children are very early risers) to find FIL sleeping on the couch. Once the children were rampaging round the living room he told me he was going upstairs to sleep in the children's double bed.
Our children's sleep can be a bit chaotic when we stay at theirs and I have a bad feeling there will come a point when they are sleeping in their double, and FIL will want to sleep in OUR guest room - i.e. the bed I sleep in. AIBU to flinch at this? And how on earth can I possibly say no?
