The monster I once called my Step Brother

Once upon a time,
Many years ago,
You were my caring older step brother,
How could I let my eyes see your lies.
I thought you cared about me,
I thought you were there for me,
But now I see the monster,
The monster that has turned you so cold.
You used to treat me with respect,
But now all I get is cuts and bruises from the punishments of my wrongs.
Everyday you abuse me,
Everyday you don't care,
Even when i'm pleading on my knees,
You slap me across the face and show no sympathy.
