A country club is like a big playground for grown-ups. Instead of slides and monkey bars, there are golf courses, tennis courts, swimming pools and restaurants. Only people who pay to be members can go inside and play. The country club is like a secret club that you can only join if you know someone who is already a member. It's a place where people go to have fun, meet new friends and relax with their families. Just like you have to follow the rules when you're playing in the playground, you also have to follow the rules when you're at the country club. That means dressing nicely, being respectful and not breaking anything.
