I explained I
Since these comments two other people I know have been bereaved and I've not noticed they have complaints about receiving nasty remarks from people they know.
Be with people who make you feel good - that is the best advice. 2017 is a new year. Time to cut the cord. It's mum's memorial service on Sunday and ten weeks since she died. She would never have been so unkind as to make unpleasant comments after someone had been bereaved. That's a fitting memorial to her. I've learned a lot about people since her death.
