Dad is 88 with dementia and an alcoholic (controlled amount by caregiver). He has a BIG house. 3bed/3bath. Huge livingroom, kitchen, lots of space. House on an acre in the country where the kids could play. But daughter and hubby are having problems; marital and financial. Looking to take the pressure off. Dad says they can live there for free. He's lonely and wants company. Probably afraid to be alone at night too. I think it's a bad idea all around. The memory issues, the no bathing, the addiction to alcohol (he doesn't drive anymore) but is always asking someone to get it for him. What are the pitfalls you can think of?
