What are conventions?

A convention is just a special rule that helps people do things the same way, like how everyone knows to stop at red lights.

Imagine you and your friends are playing a game with blocks. If no one agrees on how to build, some might stack them tall while others lay them flat. But if you all agree that every tower must be built from bottom to top, then everyone can play together without confusion. That agreement, the rule about building towers, is a convention.

Sometimes, conventions are like a secret language only certain people know. For example, in many countries, when you want to say "hello," you wave your hand. But if you're in a place where people use a special greeting, like bowing or shaking hands, that’s their convention.

Think of it like sharing toys: if everyone has their own way of playing, it can get messy. But with conventions, we all know what to expect, and that makes everything easier, just like having a shared toy box!
