ELI5: Explain Like I'm 5

Norm (social)

Norms are rules that tell us how to behave in different social situations. They are expectations that everyone in a particular community or culture share, so that we can all understand what behavior is appropriate. For example, many American families sit down at the dinner table every night and say a prayer before eating. This is a norm that tells us it's important to sit together at dinner and say a prayer. A norm such as this can help everyone feel close and connected.
