A Tear Behind Every Smile

It's a very precious thing smile,
Which helps us travel a mile.
But who knows that one tries hard to
Hold back the tears and smile for a while.
Every creature has to face pain,
As they say "NO GAIN WITHOUT PAIN"
Sometimes efforts just go in vain,
Like the dust on the road is washed by the rain.
You smile once everyone is glad,
You frown for a while they say you are mad.
Life is always not happy, because sometimes it's sad,
And people say one 'sweet smile I wish I had.'
Those are the ones who miss their dear ones who are not near,
And for them who hold back their every tear,
They look back for a while, smile, and then say there is A TEAR BEHIND EVERY SMILE...
