My auntie and I have always laughed off the fact that the women in our family are sadly lacking of tact and thinking before talking. I try to take into account other people's feelings before opening my gob, but I know I say things that out of context sound mean.
My mum has taken this to a whole new level. She is deeply insensitive and says things which I think many people would find rude or upsetting, I'm pretty sure there's nothing malicious there but my DH and MIL think differently.
Example 1 - With my MIL in the car she moans for ages about how far my Dad has parked from the supermarket (she is in good physical health btw) and while walking round the supermarket with MIL calls my Dad a horrible man and comments that soon he'll be dead. My MIL was rightly horrified.
Example 2 - Said to my Auntie, whose husband died a few months ago, at least you don't have to buy as much groceries now.
I'm at my wits end with her and want to tell her how rude this is but she is so defensive and she'll know we've all been discussing her behind her back. My MIL has decided she really doesn't want to spend any time with her in future, how can I talk to my Mum about this?
