Assur groups are like rules that people follow so that they can be good and responsible. Imagine playing a game with your friends where everyone has to follow the same rules so that the game is fun and fair for everyone. That's like what an assur group is. It's a set of rules that everyone agrees to follow to make sure that everyone is being good and responsible.
Sometimes these rules are about big things like not hurting other people or taking things that don't belong to you. Sometimes they can be about little things like not talking while someone else is talking or always saying please and thank you. The important thing is that everyone agrees to follow these rules so that everyone can be happy and have fun together.
So just like how you follow rules when you're playing a game, an assur group is a set of rules that people follow to be good and responsible in their everyday life. It helps everyone to be happy and get along with each other.
