Why do different cultures have distinct greetings and gestures?

It’s like how different kids have their own special way to say “hello” when they meet at the playground.

Cultures are like big groups of friends who live in the same place and share the same habits, just like you and your classmates. When people from these groups meet each other, maybe on a trip or when making new friends, they use greetings to show they're happy to see one another.

Sometimes, they even use gestures, like waving hands or bowing, which is like giving a high-five but with the whole body!

Imagine you have two best friends: one lives in a place where everyone hugs when they meet, and the other lives somewhere people shake hands. When your friends visit each other, they might start doing what their own group does, it’s just how they say “I’m glad to see you!”

That’s why some cultures use kisses on the cheek, while others use a wave or a bow, it's all part of how they welcome people into their world.
