"It's the same thing my life is now, ma'am," Desi thrust the notebook into the middle of the desk. Mrs. Amanah, who is also a math teacher, smiled bitterly at the sight of a straight-line equation with variables self-defined by Desi, x1: education, x2: intelligence. What caught his eye was the constant a: sacrifice. "Education requires sacrifice, ma'am. Sacrifice is a fixed value, constant, unchanging." That said, based on research in the middle of nowhere, generally the idealism of young people who have just graduated from college lasts for at most 4 months. After that they would become complainers, grumblers, and abusers like many others, then be sadly dragged down by the torrent of the great river of routines and bureaucratic pleasantries and then submit to a bad system. In the reality of such a life, how far has Desi dared to maintain his idealism of being a math teacher in a remote school?
