Say you promise to be at your desk in the evenings from seven to nine. It waits, It watches. If you are reliably there, it begins to show itself - soon it begins to arrive when you do. But if you are only there sometimes and are frequently late or inattentive, it will appear fleetingly or it will not appear at all.
Why should it? It can wait. It can stay silent a lifetime.
–Mary Oliver, from A Poetry Handbook
