There are many people I've met and known in my life, who I expect I will never meet again. Placed in its full context, this is an odd thought.
Those people I once knew are now just specks in the rear-view mirror of my mind's eye, as they, and I, hurtle by different paths to personal oblivion. We met once, but we are now separate, and in a finite time, they, and I, will cease to exist, and perhaps an infinite time will then pass during which our meeting will never be repeated. Viewed in that context, those transient meetings and acquaintances seem remarkably poignant.
