Okay kiddo, so there are some people who live in a country called North Macedonia. They call themselves Macedonians, but some people in a nearby country called Greece also say they are Macedonians.
The reason for this confusion is that a long time ago, there was a country called Macedonia that included parts of both North Macedonia and Greece. So both groups of people feel like they have a special connection to the name "Macedonian".
But even though both groups of people have a similar history, they have different cultures and speak different languages. So it's kind of like how you and your friend might have the same name, but you're still different people with your own interests and personalities.
Sometimes there are arguments between these two groups of people because they both want to be recognized as the "real" Macedonians. But it's important to remember that every person and culture is special and deserving of respect.
