Lying Teachers and Sentence Imitation

"Antigua is a small place. Antigua is a very small place. In Antigua, not only is the event turned into everyday but the everyday is turned into an event. (Here is this: On Saturday, at market, two people who, as far as they know, have never met before, collide by accident; this accidental collision which the two people stand at opposite ends of a street and shout insults at each other at the top of their lungs. This event soon becomes everyday, for sometimes by accident, sometimes by design, the shouting and the insults begin.) But event turned into everyday and everyday turned into event do not remain event and everyday, in a fixed state. They go back and forth, exchanging places, and their status from day to day depends on all sorts of internal shadings and internal colourings, and the forces manipulate these internal shadings and internal colourings are kept deliberately mysterious and unknown." (56) -Jamaica Kincaid, A Small Place

Certain teachers lie. Certain teachers are liars. These teachers, tell you something to win over your first impression of them yet they won't actually follow through with it. (This is how it goes: if you have a problem, with homework, classwork, anything, I can help, email me; when you actually email them with your problem you are instantly shot down with being told that their class should be priority over all your other classes and activities. This isn't right, he/she isn't going to help me, those were lies, this person is in fact a liar.) I don't understand why this teacher would tell an entire class to only earn the trust of everyone, and then crush it. Misleading students from day one, where is the logic, it really just doesn't make sense my brain can not connect these two ideas to fit in an logical point.
