When I was 15 years old, an unforgettable event happened to me. At this time of year, April, I went to excursion to Gyeongju and I was looking forward to our last trip in middle school. The night of the first day of the excursion, my room friends and I played simple games called "I am ground" and "Truth or Lie." After that, I heard the sound of clapping and laughing from the next room, so I suggested that we transfer to the next room. Everybody agreed and A-ram, who is my best friends, proposed that we play pillow battle with next room friends. All agreed that an interesting idea, so we grabbed pillow in one's hands. When we were leaving our room, an instructor came upon. We were surprised by the entry of the instructor. At the moment, his eyes rested on the white pillow in my hand. He asked me "where are you going and what are you doing now?" I was very embarrassed, so I hesitated and then said. "I'm just going to the bathroom." Everyone laughed at my comical remarks and I also couldn't keep myself from laughing after speaking like that. He again asked me "the pillow is a toilet paper to you? your toilet paper is so big!" The instructor knew all through that I was lying. Next morning, the instructor bid me stand still and raise hand. The event left me with unforgettable memory and a funny memory.
