First and Last

The Truth is Time doesn't lastand things of today are already the past.
One moment we breathe.The next we die.
One tear shedbutthe cheek is dry.
First comes a wealth of Fire,heat brings a drought,until it all seems dire.
Then comes the Rain -a resounding downpour -until it all drains,a drowned world no more.
In summary, our world always endsand yet,the end of one world is where another begins.
