Imagine a game of catch between a toddler and a professional baseball player. In a reciprocal game, the ball will pass steadily back and forth between the players. That doesn't necessarily mean that both players are performing the same movements or doing the same amount of work. The toddler's throw may be so weak that the baseball player must run forward to catch it, while the latter must grade his throw so that it doesn't go over the toddler's head. The toddler and the professional are not making equal contributions, but as long as the ball goes back and forth between them, they are having a reciprocal game. Reciprocity is about acknowledging and responding to someone else's actions, not necessarily about how well this is done.
