Okay kiddo, so a joking relationship is a kind of friendship where people like to play and tease each other. It's like when you and your best friend make silly jokes and poke fun at each other, but you both know it's just for fun and you still care about each other.
Sometimes, adults have joking relationships too! They might pull pranks on each other or say funny things to make each other laugh, but they still have a strong bond of friendship. It's important to remember that in a joking relationship, everyone is having fun and no one is getting hurt or upset.
