Why do different cultures have distinct greeting customs?

Different cultures have distinct greeting customs because people from different places learn different ways to say hello.

Imagine you're playing with your friends in a big park. Some of them wave their hands when they see you, some give you a hug, and others just shake your hand. That’s like how people in different parts of the world greet each other, they use different actions based on what they’re used to.

When kids grow up, they watch how adults around them say hello. If someone in their family always kisses their cheek when greeting a friend, that kid might do the same. It’s like learning how to tie your shoes, you copy what you see.

Some greetings are loud and full of energy, like shouting “Hello!” or giving a big hug. Others are quiet and gentle, like saying “Good morning” with a smile. This happens because people in certain places find these ways more comfortable, just like how some kids prefer jumping on the bed while others love reading before going to sleep.

So, greeting customs change from place to place, it's all about what feels right to each group of people!
