142 The Nonverbal Advantage
Hold the other person’s hand a few fractions of a second
longer than you are naturally inclined to do. This
conveys additional sincerity and quite literally holds the
other person’s attention while you exchange greetings.
Start talking before you let go: “It’s great to meet you”
or “I’m so glad to be here.”
Make sure that when you break away, you do not look
down (it’s a submissive signal).
In today’s litigious, cover-your-behind, i-dotting and
t-crossing society—especially a business environment where
e-mails and blind copies contribute to a culture of blame and
mistrust—there remains the world of New York diamond
traders, where much of their business is done on a handshake.
Something about that must make them feel pretty good.
