On High School Teachers

My math teacher is basically on the same wavelength as the students. They seem to be in their 50s (or so I feel), but they never extend class time and seem to just want vacation and not come to school. Teachers are also people with money, right? Maybe they're just bored and playing teacher because they have nothing better to do. But they teach well, better than someone else, though I won't say who. I don't know if they're the physics teacher, and I don't know if they only told cold jokes and read the textbook when I took their class in 11th grade. Math B doesn't seem much better either. I feel like there isn't much difference from A.
