The Author's Theme is time and the understanding of the preciousness of it.
We don't always appreciate time and life the way we should. We always need something from time, whether it is less time or more time. We have plenty of sayings for the idea of time: time flies, out of time, bide one's time, make good time, on borrowed time, ahead of one's time, kill time, in the nick of time, have a good time, time will tell, passing time, it's only a matter of time, running out of time, on time, all in good time, one at a time, time is up. We ask so much of such a simple idea. If we just took each moment by itself, we could appreciate life so much more.
