Something that took place in school

"Never judge a book by its cover" that is what i learn from a shocking event today which happened in my mother tongue class.
John ( a fake name) had been a quiet guy ever since i knew him. He never speak more than three sentances in class thus our classmates and even the teachers treated him as invisible. He got rather fair skin, cold and unblinking eyes dwarfed by a set of gold-rimmed glasses. He did not have any friends and so my friends and i thought that he was just shy. Today, what happened in class changed my opinions towards him. During the chinese lesson our teacher suggested that we will have spelling on the new characters we just learnt and if you are not able to write it out, you had to write it a hundred times. John was told to write out a certain character however he did not remember how to write it. In anger, he threw the maker onto the ground. My jaws dropped in shock and eyes boggled at what i saw. My teacher was too stunned for words and was transfixed to the ground. There was an eerie silence in the class when the bell rang......
Our teacher simply packed her books before ambling out of the class. This is based on a true story happening in my class just with a little changes in words.
