"Why the sky is so blue, not red?"
A little boy who sat beside her,thinking
"Because if it's red, someone's gonna be sad."
Then the little girl asked,
"Why did we smile when we're happy?"
The little boy replied,
"Because we can't smile when we're sadly."
The little girl asked, once again
"Why can't we turn back the time?"
The little boy paused,then replied
"Because, time never waits for anyone."
