Time. Time is a reminder… a reminder of events past. Time represents now. As time marches forward, you are there along side it… never to leave its’ side. Yet, the future is always there and acknowledged.
Meteor. A meteor will cross the sky. It reminds you of the past where the same meteor hurled across space. While the same meteor has changed over time, its’ condition now is a reminder of the present. The future is always in mind… as the same meteor will surely bolt across the sky.
