Handshaking is a common nonverbal greeting gesture where two people grasp each other's right hands. It is used to introduce oneself, congratulate someone, or agree to work together. There are typical steps to a handshake including extending your right hand, wrapping your fingers around the other person's hand, squeezing gently once or twice, and holding for 2-3 seconds. Different handshake styles can communicate different messages like friendliness, dominance, or lack of interest. Factors like culture, gender, age, and the situation affect handshake etiquette and interpretation.
