The worst part of Dementia is:
As you morew and more lose more and more parts of your old personae, your family, that has to deal with more and more demanding change of habits and erratic behaviours make your family begin to partly despise you at times, when you, as an example, walk out of your home, maybe even in underwear, and roam the streets of your city, or when you are, already in a home for people with dementia, because you can't be cared for by your wife, who can't guard you 24/7, and you begin to walk into other patients rooms, or you walk around in pants, full of your shit, it gets so hard to still see beyond this and realize, it is not yyou that does this, it is the Dementia
In a way, I was glad, when my godfather died. His daughters and his new wife had begun to fight over petty things, one of them mad at her, because now the monthly 500 Euros support he still paid her were gone, and so on.
It is a rough way to part with life
