So much of who a tennis player is can be observed in how they wait. As an audience we tend to focus on the power of the forehand, the grace of the volleys, and the dizziness of back and forth flight--you know, the whirlwind of the moment--that periods of incubation between each serve slip from our memories, like a yolky membrane running through our fingertips. But, it is in these moments that a player's identity is hatched and nurtured, that their personality grows warm enough to survive and endure.
