OMG..... why we waste time here. If you feel like crying then you cry and if you don't feel like crying please don't cry. I think you are mistaken here. Because people cry not only when they are sad or happy
Some they cry for pain, Some they cry for jelousy, Some they cry for work, Some they cry for hunger, Some they cry for money........ it never ends......come on don't go tothe depth of God Creations.

That's how it is and that's how it will be.... Don't waste time.

Have a good day without cry !!!!!
