you become aware of your own mortality staring out a window at 8 in the evening like the dog does when he's tired
seeing the trees bathed in sunset hues and the man mowing across the street the road, weather-beaten with some rickety car rattling along it and the realization that this will one day be completely gone.
you become aware of your life and the ending of it washing the dishes and thinking of friends of television shows of what you're going to eat for dinner
heart speeds up, sponge slows down and the knowledge that all of this pass and fades creeps into your brain. the knowledge itself is, of course, passing and fading; such is life.
you become aware of dying when you smile when you laugh surrounded by friends family making memories that will be lost to the dirt surrounding your bones sooner or later.
