In the United States, people are very informal at home. For example, they often wear comfortable clothes like T - shirts and jeans. They also often use first names when they talk to each other.
When Americans meet for the first time, they usually shake hands. But in some situations, like when they are friends or family members, they may hug or kiss on the cheek.
In business situations, people are more formal. They usually dress in suits and ties. They also use last names and titles to show respect.
In other countries, customs are different. For example, in Japan, people are very formal in both business and social situations. They bow to each other to show respect. The deeper the bow is, the more respect is shown.
In many Middle Eastern countries, men and women have different customs. Men often greet each other with a handshake or a kiss on the cheek, while women may only nod or smile.
