I love the poem.
I truly believe some people have a saintly capacity to deal with dementia in others. I am not one of them. This makes me feel guilty when I remember times I've fallen short of the standards to which I guess a good person should aspire.
But sometimes I wonder if we beat ourselves up excessively for not being perfect. Not everyone has it in them to be saintly. The rest of us just have to make do with the best we can do.
And I hope that in a small way my writing may provide some small recompense to the world for the good I wasn't always able to do directly.
