If we were to list characteristics of any family gathering, one defining tradition would be that of a good, long, sometimes loud, and always a hoot, laugh. It was usually proceeded by some story, comment, or just looking at each other with the look of "I know a secret". Remember Mother laughing until she cried?
When Ann lived in Olympia, there was an ailing lady in her ward, that requested to hear her laugh. She said it would make her feel better.
In this case, Paul Tanner, who is a great story teller, and Dad are in the middle of it. No wonder that Dad lived a long life. And Paul has had miracles in his own.
