What would you think if I threw a dictionary at the student because he didn't know the answer?
That's pretty messed up. You'd literally throw a dictionary?
Not really. It's just that I hate the student and the student was just unlucky for getting me as his teacher.
You should not throw things at people. It is not only dangerous, it is also illegal.
If I wanted to throw a dictionary at the student, I would have already done it.
It's never okay to throw things at people when you're mad, especially at a student. You should find better ways to deal with frustration. Maybe try some yoga or meditation at the end of the day.
