In the movie To Sir with Love, Mark Thackeray (played by Sidney Poitier) was a new teacher at a school where he went through abuse and also harassments of all sorts by the students. He was given a better offer at a far better school. Then he went to the goodbye ceremony of the students who were now ready for life and ready to carry the torch of education because of his tireless hard work and dedication.
When Mark Thackeray took an abrupt break from the ceremony and went back to the classroom, two spoiled students entered into his classroom and mocked him, telling him that he would see a piece of them. Right away, without thinking twice, he opened the envelop that had his job offer and he ripped it up.
Why did a teacher who went through such intense harassment from the students, and knew for sure he would go through more of it again, do that? Why did he stay back at that current school and choose such an option that could have been altered by a better choice of going to another good school, maybe with higher payment, where students were nothing like what he saw during the last study year?
