I'm so sorry. I don't know what it has to be like this when we get older. My father-in-law was a very kind, generous man. With dementia, he got angry, stingy and mean. I think they're so confused. For some reason they think they're being taken advantaged of. Sigh...........

Any chance that you can get a break next summer? I know your siblings live far away, but could 1 or 2 of them plan their vacation in your area? Let them spend some time with him and give you a break.
