Why do we have to be sad? He had a glorious, near perfect life, and accomplished so much, lived long and healthy, had childfren and grandchildren, and the love of a good woman..It was his time, God called him home. There is NO need for sadness..
Sorrow for his family’s loss and the loss to the country; he is in a better place and we can all be thankful for that. Your point, however, is well taken.
I am sad for the end of an era, sad because we won't see his like again, and sad for his family. I am certain that Nancy is sad, and I am, too.
But in the sense that he lived his life to the full, with honor, and that he is now released from the prison of Alzheimer's...you are also right.
The sadness is from his leaving us in this world.
