Imagine you are on a playground, and you spot a giant, old-school teeter-totter. It's bright yellow and it rises well above your head on the upside. You look around the playground, find someone who looks well suited to be your partner and together you climb onto your opposing seats. Rising and falling, you bounce up and down, enjoying the ride. Feeling confident that you and your partner have found a good rhythm, you tuck your feet up off the ground, trusting that the balance and rhythm will continue. Then, just as you begin to relax in your new position, your partner, across from you and on their way back to the ground, turns their legs to the side and casually rolls off their seat as they touch the ground. High in the air on the other side it hits you. You're about to come crashing down.
