She Is A $*&^"What I've learned from my past experiences is that you harvest what you sow. People live life crushing people and being selfish and being just plain evil. Evil thoughts harbor evil energy. All of this will just come back to you at a certain point and make twice the damage. I am sure and aware of this.
Bad vibes do exist and they reverberate and haunt us if we let ourselves be dominated by evil. Bad actions equal bad results giving us bad feedback. Life is a boomerang, it all comes back to us.
