Though now I am a college student, but I still remember many things in the primary school and one of it is always kept in my mind. As a schoolboy I was used to be very lazy at school, and I played a lot after class but did few in class. One afternoon before school was over, our head teacher was giving us last class, while I fell sleepy. He went on teaching without wake me up. When school was over, he asked the else students to leave the classroom quiet, leaving me locked in the classroom. You can imagine what hard I cried for help when I finally woke up.
