What is sadness?

When I am listening to sad songs or movie, of course I feel sad.  In layman's term, we call it 'emotional'. But hey, it's normal since human has emotions. But sometimes, you just feel sad out of nowhere and without a reason. The feeling just strike you and without knowing it, you are immersing yourself in the pool of sadness. Your facial expression defy you and your surrounding people started to question you. You then start to doubt yourself and your own validity. You become tired. You start to link it with so many things and it makes life sadder than it is now.

It's a feeling. Human emotion gave birth to it. Some say it's a gift and some say it's a nightmare. For me, it is a feeling that we cannot avoid, delete or erase. And there is nothing wrong to feel sad. People tend to relate it with negativity. Sadness makes a person fragile, and then stronger. Sometimes, we just have to undergo that phase of life, so that we can grow in maturity. And you know what, we just have to grow with it, live with it and be part of it.
