Ironically, it was done by my mother and brothers and all because of some misunderstanding. Since 2005 after Mom's near-death experience at St. John's, Simon (stepfather) and I never left her alone. I came over once a week and deep-cleaned their house because I knew that would make Mom feel better. I changed and washed sheets so the beds were fresh.
Larry and I both drove to the store for them, mowed the yard so Toby, Mom's Maltese, never had to have high grass on his belly. Larry and I had Mom and Simon's welfare above our own and felt 100% responsible for their well-being for three years 24/7. Only someone who has experienced Care Giving of Parents could understand how exhausting that is.
Then Simon passed away.
And a whirlwind of family hatred came down on us and blew our life into little pieces; I believe the ones doing this would have utterly destroyed us both if they could have. I have always lived right down the road Mom; the brothers have always lived in other far away states.
