Notice the two buttons on top the clock. Make your first move, press the button on your side of the clock and the other players time starts to run. At the same time, your clock is paused. Now, when the other player makes their move, they will press the button on their side which stops their timer and starts yours simultaneously. EVERY time you move, you will press the button.

Just as in life time is limited in co-productive relationships. Each player has a choice about what to do in their limited time together. A more equal productive relationship is possible but it needs both players to prepare, be open to new experience and learn.
