How to name it...!!

Compare it to the tenderness of a dew,
Doesn't actually work with all but a few,
When words don't say it all under the hood,
Still you would be understood...

Just a smile or just a tear,
You would want to share,
Neither hopes, nor expectations,
Its pure and beyond words limitations...

If they say diamonds are forever,
I wonder who's that fool..so clever,
More precious than the biggest diamond,
Is a true heart that cares, a friend...!!!
