I got full of bloody all over my running shoes and leggy. I refused to leave and stayed stood up and staring.. (cuz I was in deep shock) The officer of TTC (Toronto Trainist Commisoner) asked me you have to leave.. I said NO!, I want my Daddy, He is works TTC head of quarters in Greenwood Dept. TTC officer shocked and knew who is guy that he is my Dad.. Called to my Dad come over to the station where I was stayed there. My Dad brought brand new running shoes and new clothes too come from TTC's expense covered it for me. He was interpreting for me to talk Police officer.
