Knife Man

He came at me with the knife, and I knew he was there.
He kept walking round and round me, not passing without a stare.
What could I have done, how was I supposed to stop him?
He held onto my shoulders, with what I prayed was just a pin.
Everytime I made a mistake, he would slash my back.
I thought I was a gonner, leaving Worthing in a sack.
All he wanted was a kiss, and to touch me all over.
But I kept fighting back, waiting for it to be over.
He knows me, but I don’t know him...
How could I report it?
