Sometimes people think it's the students that ae the most challenging part of a teacher's job. That's only true most of the time. It can actually be the parents trying to interfere too much with their kid's education. Sometimes a teacher can just look at a finished project and go, "looks like dad did a great job." Sometimes it goes the other way. Sometimes teachers have no faith in students but they succeed anyway, like this student who won an art contest to spite their rude teacher.
