Haha, it proves you deserve nothing to be a teacher! Look, there's only one person coming in, and see how you act. You done your preparation only once for a year right? You come in with, what the heck, short notes in your palm? Funny. And then, what the, Mahjong paper? You really good in acting, pretending to a professional teacher. Ya you have no good value, in fact you love to insult other people. You like to scold people publicly, and now see how you do in your 'presentation'. "Can anyone give me an example?" don't you think this is disgusting? You never ever asked us right? You'd like to ask anyone randomly to answer your silly question, and today, start to speak softly and politely? Stop pretending, we know your attitude. If there's no one watching your show, i guess you're not going to do anything and waste a period. Right, Mr Kong?
