Handshaking is a common social gesture where two people grasp each other's right hand and move it up and down. This action is often used as a greeting, farewell, or sign of agreement. It can convey friendliness, respect, and trust between individuals. In many cultures, handshaking is an important part of formal introductions and business meetings. The strength and duration of the handshake can also communicate confidence and professionalism. However, customs around handshaking may vary, and some people may prefer alternative greetings, such as a nod or a wave, especially in different cultural contexts.
