To all who responded to my request for a PD Glossary, many thanks. Your efforts helped to clear some questions we had. Re: humor--I've enjoyed most of the humor postings. I've added them to my Humor File. Here's a couple of quotes: Laughter is the shortest distance between two people.--Victor Borge Life is a tragedy when seen in close-up, but a comedy in longshot.--Charlie Chaplin You cannot prevent the birds of sorrow from flying over your head, but you can prevent them from building nests in your hair.--Persian Proverb Don of W.PA.
