I have a teacher name Mr Kam. He is actually not a human. Sometimes, he were scolded by other teacher and he just keep quiet. Not only that but there is one day we peep on him in the toilet and saw his eye turn completely white and his teeth turn so sharp. We suspect he is immortal.

But now, he didn't teach us in the school anymore cause we know that he is inhuman.

How do you explain this monster or human????
