Highschool days remain in my memory. My school is in pusan, my hometown. There are crude and emotional people. The same applies to my teachers and friends. Among the rest Mr.Cho, my math teacher linger in my memory. He was in charge of my class. He was a strict teacher and had a nickname 'horse's nose' because his nose looks like it. Anyhow every student stand in fear of him. So, some students play a trick on their class mate by various means. For example, they disguise teacher and open the front door with a bang. If that happen every student quiet down then they were giggled. But it is habitual. One day someone open the front door with a bang again. I pissed off and said "Horse's nose! Why are you come again?". By the way, a quiet stillness prevailed. Mr.cho stood in front of me when I looked up.
