Once I asked a question,
Why do we write poems mostly when we are sad and not when happy?

I think I get it now,
Happiness is a sweetness,
Which can be shared.
But unhappiness is that bitterness,
Which we tend to keep within ourselves,
Everyone understands sweetness,
But bitterness has its own variation,
Which isn't known until YOU taste it.
So we rely on our ways to express it.
