Teachers a dreadful species

Why do some teacher think they are above question?  A generalization about teachers I've noticed to be mostly true.  I have found them disappointing to deal with in the real world.  Yesterday after having to contend with an excessively disagreeble teacher, my anguish subsided when the next customer was enjoyable and fun.  She was a lunch lady.  --her words--   I'm not sure what coronation ceremony takes place that crowns teachers as royalty. I'm sure it is some sort of psychosis, waiting to be labelled.  Whatever it is it must be a horrible affliction to have to create scenerios to roll play as a Royal forced to walk amongst peasents.
