The Weight of Tears

What tears weigh the heaviest would you say?
Is that the tears of sadness or from bygone days?

Would it be the weeping of destruction and war?
Or the wants of the days before?

Is it the tears of loss and grief?
Or the wails of disbelief?

Maybe it is the tears of abuse,
always left with another excuse.

Or the sobbing of a broken trust
or having to adjust.

Is it the howls of despair
or life being unfair?

If you ask me what is the heaviest tear. I would say it is the ones that no one hears.
