wrong impression

There was a teacher that I had in the 7th grade, for a health class, and the second class of the year I was late due to locker problems. So I Had arrived to class and the door was shut. So I knocked and a student let me in, and she pointed to the door and had me go out in the hall with her. She pinned me up agenst the wall and started lecturing me with a harsh tone. She said that this better not ever happen again or there will be a punishment. I told her I was not the TYPE to be late and that I had never been late. So she listend to be and after that she has always liked me. The teacher is Mrs. Hood.
