Fifteen to twenty people in a classroom busily writing an exam. Well most of them. A squad member walks in. Pretends to see if anyone is copying and almost robotically(if thats a word) moves towards the last bench. Picks up A's question paper and says "Whats this?" A says "Just some stuff on my mind." Squad member "next time I'l throw you out!!". A mumbles.
Squad member gets back to pretend checking. A gets back to writing. Now with a frown on the face. Squad member walks upto B and smiles broadly. B grins back. Squad member smiles at C and C is too happy to be acknowledged. Squad member walks upto to the door. Throws a second glance at A. Notices A has returned to writing and leaves.
Who am i? Onlooker D. What did onlooker D see in all of this?? A had innocently scribbled stuff FAR from the examination paper on the question paper. B and C had chit booklets in their pockets which they used to copy when their very friendly squad member left.
What was D left feeling? That D had just witnessed what very often happens in the world outside as well.
You smile at the devil and suspect the innocent one.
