premise: I know this is only my second semester here , but this is my third class I ' ve had with him and I think he inadvertently became my favorite teacher because of it . He was one of those calm , laid - back type of teachers who really valued creativity . He graded hard , but then , who does n't at this school . I was really looking forward to this class with him too . What may have caused him to become your favorite teacher ?
hypothesis: He did n't grade hard .
