Okay kiddo, so sometimes grown-ups get together and have meetings to talk about important things. The Tuesday group is just a name for a group of people who have a meeting every Tuesday to talk about politics and issues that are happening in the world. They may have different opinions and ideas, but they all want to work together to make the world a better place. It's like when we have show-and-tell at school and everyone brings something different to share, but we all listen and respect each other's ideas. The Tuesday group is like that, but for adults.
