My friend has become mean since getting diagnosed with Alzheimer’s disease

DEAR ABBY: An old friend of 50 years has recently been diagnosed with early Alzheimer’s. She’s still conducting her life as usual, driving and taking care of her banking, etc.

However, she has lost her filter and talks to me about my figure (“Your thighs are shockingly thin”), and also my health (“Are you going to die? My mother had a cough like that, and she died”).

I am struggling to control my anger at her presumptuousness and holding myself back from some very apt and mean comebacks. I don’t seem to be able to let this go.
