Social norms are the unwritten rules that guide how people behave in a society. They help us understand what is considered acceptable or unacceptable in different situations. For example, saying "please" and "thank you" is a social norm that shows respect and politeness in interactions with others. These norms can vary between cultures, meaning what is normal in one place might be unusual in another. These norms influence our daily lives, shaping our actions and decisions. For instance, in many places, it is a norm to greet others with a smile or a handshake. By following these social norms, we create a sense of community and belonging, making it easier to connect with people around us.
