My voice was heard

I am inside society,
but you did not
recognise me.
I spoke out loud
and my voice was heard,
but my words not understood.
I realised, that you see
with your open eyes
but with a closed heart.
When my tears were rolling,
you thought it was raining.
When it was silent
around us,
you heard my heart beating
and you thought it was
a knock on your door
and ran away.
