It sounds like it will be a better place for him, PF. It's good to know that you and your aware residents can relax. It's a shame that people have to suffer from such a debilitating condition. I feel bad for the families and friends of those patients, and thank the lord they have wonderful angels like you and all medical personnel to help them since they can't help themselves.
I hate Alzheimer's it steals some very nice people and turns them into monsters. Not all Alzheimer's victims are aggressive, but they all have those times when they can make you crazy with the repetitive things they do. Many are sweet, loving, cute and funny. I got a smile/laugh out of one of our people I didn't know could still discern humor, let alone conversation. She was laughing about me spilling her peanut butter sandwich on the floor. It was gone the next instant, but I did hear it and see the smile.
