Social norms are the everyday rules people follow in a group. They include behaviors such as greeting others, taking turns, or using polite language. These rules are learned through family, school, and culture.

In some countries, people greet with a handshake, while in others a bow or cheek kiss is common. Eye contact, personal space, and gestures can also vary between cultures. Some norms are written, like school rules, while others are unwritten customs.

Social norms help organize behavior in groups. They can change over time as societies develop.
