Days of smile and grace

Does it belongs to you or me.
it doesn't matter we are we.

Rain ,pain and blood meant to flow.
sometime silence doesn't need a blow.

Look of past hurts and future scare's.
Being right here is biggest of dares.

i can deny it is not good bye.
hope words can digest this lie.
