The wonders a simple sentence can do.
It's truly amazing.
Nothing less of a miracle.

The 3 words, " I need you", gives someone the courage to live on.
It makes the person feel... Needed.
And important.
It makes that person give up all thoughts of giving up.(Pun intended)

It is yet another wonder, as to how a doctor holds the life of someone in his hands.
I bet every surgeon who undertakes an operation shakes in fear.
In his heart, of course.

What you say and do, affects everything in a direct and indirect way.
Calling someone "useless" or a "trash" really crushes a person.
Direct, or indirectly.
Maybe one at a time doesn't work.
But over the years, it accumulates.
And finally when the person falls into a state of anguish.
All these words show their effect, and they might ruin a recovering heart.
Be careful of what you say.

You never know what it might cause.
A simple sentence or two can change the life of someone.
Be it "I need you", "You're useless, or "Disappear from my sight".
Or maybe even the clinche 3-word phrase of "I love you".

Still, never say anything if you don't mean it.
To speak is to speak from the bottom of the heart.
Empty words are meaningless.
