Imagine you and your friends have a club where you meet often to talk about things you like and things you want to do. The Catholic Church has a club like that too, called the Synod of Bishops.
The Synod of Bishops is a meeting where important people in the Catholic Church, like bishops and other leaders, get together to talk about important things that are happening in the Church and in the world. They talk about how to make the Church a better place and how to help people become better Catholics.
Before the meeting, people all over the world are asked to send in their ideas and opinions. These are called "proposals." During the meeting, the bishops talk about the proposals and try to come up with new ways to solve problems and improve the Church.
When they finish the meeting, they make a report that they send to the Pope, who is the leader of the Catholic Church. This report is like a big homework assignment that tells the Pope what they talked about and what they think should be done next.
In short, the Synod of Bishops is like a big club meeting where important members of the Catholic Church talk about how to make things better for everyone.
