I remember when I was a young kid, going out in service with my dad. We were passing out invitations to the convention, and my dad had what seemed to be a good conversation with the householder. They talked for a good ten minutes. Finally, my dad handed him the invitation, and the man seemed genuinely interested. As I was walking back to the car, I turned around and saw the man crumple up the invite and throw it in the trash. A waste of time and paper, indeed!
