Explanation:
Chris entered into the university at a very tender age, a not so common one in our community. He was only fourteen. As every young boy would aim, Chris was determined to finish at the top of his class at graduation. On getting to campus, Chris started well by facing his studies but not without the childish euphoria that he achieved a great feat early in life.
It was so unfortunate that the room that was allocated to Chris in his first year was full of brigands and juvenile deliquents. He soon lost his dream for excellence. He started following them to clubs and partying all day without giving any attention to his studies. He started having minor issues with his academics but did not give enough attention to it. To him, it was benign. Several lecturers who took interest in him advised repeatedly but he turned deaf ears. In his fourth year of his medical school, he was rusticated due to poor performance, the least he could expect of himself. His parents went to the school to plead but it was too late. The provost of the college told Chris's parents that he had called Chris on several occasions to advice and warn him but he would not listen and it is unfortunate that the last straw breaks the camel's back.
