Name changed for this. After almost 50 years or marriage, my wife died at home, as she wished. Cancer. During her decline and death, I took comfort in the way the family all pulled together. By family I mean my two children, her three children (my stepkids), and assorted grandchildren, all adults.
Two weeks after the funeral, my middle step-daughter, in her mid-50's, wrote me a very long email, and also copied it to everyone in the extended family. In that long email she detailed a long list of complaints about me, everything from a bad joke I made at the hospital, to my wife's will, and everything in between.
Some things I might have done differently, but, oh dear...
Eventually we patched up our relationship, sort of, but things will never be the same.
