I can imagine. My dad didn't have Alzheimers, but we did think he might be heading toward Dementia. But honestly, I think it was just that he was old and lonely and didn't really care anymore. Since I'm in the Netherlands, he didn't have much of a relationship with my brother, and he lived by himself on the ranch he was born on. He was 84 when he passed in March last year, so I think it was just a matter of being tired. The things people told me he did....going out to feed the cattle in nothing but thermal underwear and cowboy boots in the dead of winter...greeting the census taker on the porch in the nude (she ran away and didn't come back), and the man never cleaned a thing. Having been to visit him in 2016, he was able to care for himself and he was completely normal as far as his social behavior goes...but that was just my dad, so I'm pretty sure it wasn't Dementia, but I can see how other people were concerned and why they wrote to me to please come and check out the situation, which I did. Now it's pretty humorous, but at the time, I was really really worried.
