Student glues classroom door shut and locks teacher inside as payback for unfair treatment all semester: 'The fire department had to come to free him'

Everyone has that one teacher who gave them a hard time in high school. If life were a movie, there would be some sort of inspirational and emotional arc to that teacher where the two of you come to understand, appreciate, and respect one another. However, in reality, there usually isn't much of an arc at all. Most of the time, the two of you end the year still resenting one another. The only real ending is one of you leaving the school and no longer being a part of one another's lives.
