Why do I cry...

When there are so many smile faces near me why do i cry? /When the Nature is green and rhyming why do i cry? /When my friends are holding my hands and walking with me why do i cry?/ When i have food to eat,house for dwelling and clothes to wear why do i cry?/ When life is mortal and i have limited number of days why do i cry?/No i will not, and never let others cry.I will smile and make others laugh, I will,I will....
