It seems like such a simple concept, yet it's remarkably difficult to achieve. 

Something as simple as throwing the ball for the dogs, restraining one so that the other can have a turn. Imposing balance and equity on an otherwise anarchistic situation.

What is balance, though, in essence? It's not tangible, invariable and prescriptive, but rather dependent on contexts, and coloured by perspective. And it is never more than momentary, ephemeral. It necessarily supposes a movement of give and take, of compromise. Perhaps that's why it's such a fugitive state. We humans aren't so good at compromise or adaptation. Perhaps the very quixotic nature of balance is its very virtue, though. It's at least something to strive toward.
