Senior year physics teacher . If you had a question , he ' d tell you to read your notes . Even if you did just that , he felt no need to explain any further . If you were late to class he ' d keep his door locked so you couldn ' t come in . This happened to me once because I was helping a teacher with something in my previous class and had a teachers excuse for it . He assumed every person that was late was just dicking off in the hallway and therefor deserved to miss class until he decided to come open the door for you . Going to back to him not answering questions , if you were late to class for legitimate reasons you got no answer to your questions about the work you ' d missed because he didn ' t want to open the door . I switched out of that assholes class before the second semester .
