Here is that link about President Reagan staying sweet and good natured. This is the article from his doctor. (The one that is an honorary pallbearer.)

Also, did either of you see the interview with Michael Reagan on Fox, yesterday I think. He was talking about forgetting to hug his dad goodbye once and he was in the car about to leave, when his wife said, "Michael did you forget something?". She then pointed to the doorway of the house and there in the doorway, with his arms outstretched for a hug stood his Dad.
He didn't really know Michael anymore, but he knew he usually got hugs from him.
That made me cry alot. The thought of him standing there waiting for a hug like that....
Michael said he ran back and threw his arms around him.
He also said that during the Christmas holidays, he hugged his dad and told him goodbye and I love you.
As he was turning to leave, his Dad yelled after him in that clear strong voice.."I love you, too."
He hadn't done that in a very long time according to Michael.
(Wipe your tears!)
Anyway, this article and those stories made me feel much better about President Reagan's life with Alzheimer's. I too have seen patients that become mean and combative, but that doesn't seem to have happened to our dear President.
