Some teachers pride themselves for teaching and some pride themselves for getting a salary. They are easily distinguishable from the way they teach, their strictness in punishment and tolerance of humour in classroom. The former are obviously much agreeable. But the problem is that you may not like to attend classes of either or for that matter any classes at all. So to save you from the dungeons of hell, I have come out with my first hand experience of facial expressions which when pulled will help you go through these classes unnoticed, undisturbed.
Teaching teachersFor them you ought to look pleasantly interested. A slight smile, eyes a little wide open and nodding gently now and then.
The other kind
A look that says I am seriously interested. A decent frown, eyes small as if narrowed with concentration. If you can manage to look totally non-kissable while pouting, then pout.
Practice at home in front of a mirror before trying the face in front of a prof.
Best of Luck!
Special thanks to Ali for being the great model for these pictures.
