Love's fate

In 4 letters, an eternal emotion is set,
It keeps millions from stopping to fret,
In 4 letters, all that makes life well,
It’s the story only the characters can tell,
It can manifest itself in many a different way,
It’s black, white, and even gray,
Hurts a million, heals a million more,
Maybe its not so patient or kind anymore,
It still doesn’t envy, nor does it boast,
It’s still the object of many a toast.
The purity, one day, will be gone,
An era of darkness, then ushered will dawn.

What ever happened to the high values placed?
On the institution of marriage, have they been erased?
A day will come when they are forever lost,
A dark day indeed, when we pay that cost.
Woe to thee who love in that day!
Why, why dost thee ignore what I here say?
Waste no time, my friend!
Love as we know it is coming to an end!
