Metatron...Good to see you back..
Having been a salesman for all of my life (although I lied to my kids and told them that I played a piano in a brothel) I don't have any problem with the WTS teaching this. This is good advice.
I made all of my kids read "How to Win Friends...etc" by Dale Carneigie. We all need to learn how to communicate. As much as I disagree with the WTS teachings, it is their right to teach their adherents how to better communicate.
Off the thread....if more folk read this Carnegie classic the world would be a better place.
