Ok kiddo, imagine you and your friends are playing a game where you have to take turns being the leader and making decisions about what game to play or where to go. Imagine each time it's someone's turn to be the leader, they stand in the middle of a circle and everyone else sits around them in a circle. That circle of people is called the director circle.
Now, sometimes in important grown-up meetings, there are also director circles. They are a group of important people who make decisions about things like what a company does or how a charity works. These people are like the leaders in your game and they take turns making decisions for the group.
When they are having a meeting, they sit together in a circle just like you and your friends did. But instead of playing games or deciding where to go, they talk about important things and make big decisions. They each have an important role to play, just like in your game.
So that's what a director circle is all about - it's a group of important people who make decisions and work together to make things happen.
