If I were a student at that class, I wouldn’t be able to concentrate for one second with that crooked projector. I might’ve even gone up there myself to adjust it, even if it cost me my grade – it would be worth it. Seriously, how could it not bother the teacher? How does he expect the students to concentrate on anything he says?
It’s not even a purely aesthetic issue, but it actually makes it hard to read what it says on the slideshow. What’s the point of putting up a projector with a slideshow if the students can’t even make out what it says? We remember those classes when a tall student would volunteer to fix the projector. Couldn’t they find one in this class?
