Don't underestimate me

"IF YOU UNDERESTIMATE ME IT WOULD BE YOUR FIRST AND LAST MISTAKE. DO NOT THINK I AM SEXUAL JUST BECAUSE OF THE PICTURE I CHOSE EITHER, THAT WOULD BE A MISTAKE ON YOUR PART TOO. I CAN SHOW YOU WAYS TO DESTROY SOMEONE WITH OUT EVEN TOUCHING THEM.  TO ROB AND STEAL AND KILL WITHOUT A SINGLE FINGER BEING LAYED. TO MENTALLY DESTROY AND THEN WALK IN AND TAKE. BUT NEVER UNDERESTIMATE ME, I WILL DESTROY YOU"
