To say, to express, to share,
to know and mostly
having some benefits
is our Nature.

We have emotions,
power to cry & laugh.

We sleep and dream.
Some people cannot
sleep until they achieve :).

We are optimistic. We got desires, fascinations & ambitions.

We are social creatures. We follow society & social commitments.

We love to get people around. We party, we celebrate. We get married and some fall in love!! .

We want to show. We have to prove. Because we are not one. We are one of so many.

We need to say. We need to say differently - delightfully - decently. In-short...

Note: Wikipedia, the free encyclopedia has their own definition
but the humans we observed are different ;)
