I HATE HIM! ok heres the story i did bad on a quiz of mine and got a 60 well he has this thing where he emails ur parents ur grades on tests,quizzes etc. and well he made a mistake and gave me a 6 outta 100 instead of a 60. Now my dad thinks im totally retarded!!! I hope he believes me when i tell him that the teacher made a mistake
