Psychology says people who have a special kind of handshake for their friends, children or family aren't emotionally distant. Many people create their own greetings with people who matter to them. It can be a handshake, a fist bump, a clap, or a sequence of simple movements. These greetings may look playful, but psychology says they have an important purpose. They help people feel connected and understood. They also become symbols of shared experiences and memories. Over time, these rituals become part of a relationship. They remind people that they belong to a group and that someone values their presence.
