You captured the loneliness of caring for someone with Dementia perfectly. Obviously, in my case there was no guilt associated, but the scene in the bath is something that only experience (or exceptionally imaginative skills ) could portray.

As for the guilt, why is it that the guilty need to unburden even in the most extreme and vulnerable circumstances? Why do people need to hurt twice? What is forgiveness? OMG…see, you’ve unleashed so many “whats”. Of course, that’s what a really good story should do, and this is a superlative example of good.
