Tears -- Expression of grief or sign of Happiness

Human nature is very diverse. It carries endless emotions and infinite ways of expressing it. One such way of expression is 'Tears'.

We cry when we are in pain, when we feel that things aren't going our way. When we feel that our strength has failed to shield us from the pins and pricks of the world. But crying makes us shed the burden of hiding our own feeling in ourselves. It relieves us from the liability of keeping the feelings inside which we think if brought to the world will prove us weak.
The tiny droplets of water become the carrier of emotions and revealers of pain.

But there's one more role for them, their presence is the sign of happiness. Tears in this case become the bearers of joy and love. We cry when we are happy about something, when we find something that touches our heart.

In our life we'll get to see and shed lot of tears of grief and tears of happiness. It is on us which ones are more in counting.
