Lexie, I completely understand.
My dad has alzheimers. It has gotten worse this past year, but he still functions in dressing himself, and can even drive up the road. However, my mom still thinks he can do things that he really cannot. Last week she had him out on his tractor, big mistake. He left it in gear when he got off and could have been really hurt. Denial is a powerful thing.
It's great they have an assisted living section, that sounds like just what he will need. Hopefully he will make some guy friends of his own as well!
