You Know Nothing

Don't do that to me,
You don't know a thing,
You try to hurt me,
But fail occasionally.
Though sometimes you succeed,
You hurt me to the heart,
I really want to kill you,
But sadly I merely fall.
Have you ever heard of others,
Of their hearts,
Pain,
And loss?
You act as if you know it all,
When all you know is the act of being cold-hearted,
Cold-hearted like the snow.
