My teacher is damn possessive

"Walk Miss Carter"he said in a angry tone.I was took shocked to listen to what Mr.williams said."I said walk Miss Carter".this time it was an order and i started walking towards his office.He came behind me.John my boyfriend was trying to talk to me but i was angry with him because he cheated on me.He grabbed my wrist and
was trying to stop me.I tried moving away from him buy his grip grew tighter on my wrist."Please let go "I yelled at him and yanked my hand away from him.He kept a hand on my shoulder to try and stop me but i tried moving away .Because of his tight grip on my shoulder my top got torned near the sleeves part.As soon as i realized that tears started popling in my eyes.I saw Mr. Williams coming towards me.
