Serial reciprocity

Serial reciprocity is kind of like a game. In the game, two people agree to do something nice for each other. They can do something big or something small, like give each other a hug, or help with a project. When one person does something nice for the other, it's called a "turn." In this game, the two people keep taking turns being nice to each other, and can keep it going as long as they want. It's a way of showing appreciation and spreading kindness.
