All Students Please Do This One Thing

While I was teaching children I also taught some adult classes. Also a few adults came to my university classes.
There was a problem which still bothers me. When students left the class they usually didn't say anything to me before going. And in most cases the management said nothing.


Sometimes I asked the other students in the class or the office what happened to that student. I think a few students told white lies saying they were too tired or busy.


I dislike being told a white lie, but I want to say that leaving without saying a word is the worst thing. I think it's rude.
Sometimes a student attended regularly for a time and then vanished without a trace. Children did this also. I will tell a few examples. One medical student attended my class for a time, spoke English well and all seemed to be fine. One day he wasn't there, then another day he wasn't there.


I asked the students if they knew what happened to him. I just remember that one student said as they left class one day he said he may have to stop coming to class because he was busy. I don't understand why he didn't say anything to me directly since we got along well. At least I understood why he quit. Many students just left me guessing and when I think about it I can't get it.


Please say something, anything, to your teacher before quitting a class!
