Knowing you are alive is feeling the planet buck under you, rear, kick, and try to throw you; you hang on to the ring. It is riding the planet like a log downstream, whooping. Or, conversely, you step aside from the dreaming fast loud routine and feel time as a stillness about you, and hear the silent air asking in so thin a voice, Have you noticed yet that you will die? Do you remember, remember, remember? Then you feel your life as a weekend, a weekend you cannot extend, a weekend in the country.

Annie Dillard (An American Childhood)
