Cheating
During my first week at my new school, I observed that cheating was
rampant. I had always considered it rather inane cheating at an exam
because of my code of ethics, and because so much was at stake.
Apparently, the other students didn't concur. Even the presence of
a proctor didn't intimidate them. Far from being a clandestine activity, 
the cheating was open and obvious.
