dh at mils house. Mil is literally alf garnet in a skirt with a voice that could grate parmesan.
Ds was talking to dh on the phone. Mil was in background shouting questions via dh on phone to ds (aged 6). Ds didnt know what the screaching was and said to me " whats that horrible noise.". Thats your bloody grandmother.
Not remotely an aibu i suppose, but i am being very U (or non u, nancy mitford style?) at being rude about mil. When shes such a loveable old homophobe / hyacinth bucket type.
