When two people meet formally for the first time, it is customary for them to shake hands. The handshake is initiated when the two hands touch, immediately. It is commonly done upon meeting, greeting, parting, offering congratulations, expressing gratitude, or completing an agreement. In sports or other competitive activities, it is also done as a sign of good sportsmanship. Its purpose is to convey trust, balance, and equality. * Pound Hug * Cross-Cultural Handshake * Secret Handshake
