Good advice, Gregg. Another approach that works is Ben Franklin’s technique of asking someone who doesn’t like you, or is otherwise difficult to deal with, for a favor. Research has shown that this works; we tend to like people who are indebted to us, and there is is also perhaps the psychological loop of “I do favors for people I like, I did this person a favor, therefore I must like this person.”
Either way, cheerfulness, compassion and humility always get you farther than argument. Thanks for the article.
