Step-by-step explanation:
When someone sneezes, saying "Bless You!" is a common social response rooted in cultural beliefs and customs. The phrase originated from the belief that a sneeze could potentially expel the soul from the body, and saying "Bless You!" was a way to protect the sneezer from evil spirits. While it is a common practice in many cultures, not all people say it, as customs and traditions may vary.
Walking on the right side of a sidewalk is an example of social norms and etiquette. It is a way to ensure smooth pedestrian flow and avoid collisions. While it is a common practice in many countries like the United States, not all people follow this rule in every culture or country.
Lining up or forming a line is a social behavior that helps maintain order and facilitates fair access to resources or services. It allows individuals to take turns and reduces chaos or confusion. If people didn't form a line, it could lead to disorder and potential conflicts as everyone tries to access resources at once. The concept of standing in a line is not attributed to a single individual but developed as a social norm.
Shaking hands when meeting someone is a common greeting gesture in many cultures. It signifies friendliness, trust, and establishes a personal connection. While it is a widely practiced custom, not all cultures or individuals shake hands. Different cultures may have alternative forms of greetings, such as bowing or hugging. The origin of handshaking is not definitively known, but it has been a part of human interaction for centuries.
