Just like my secondary school Maths teacher. I was downright hopeless in Maths and was despised by him. During a heated confrontation, he tried to slap me but I blocked and pushed him away. He was furious and threw a punch at me, but I arm-locked him. He didn't know I was trained in martial arts. Luckily, some of the guys in my class broke us up. For that, I was suspended for a week. I met that CB kia years later. He dared not even look at me. Although I failed my Maths, but got the best O Level results in my class.
