Being stricter

I was a lot more fierce today in my sec 3 class, or in the words of a teenager, bitchy. The following conversation took place after a boy said that he already worked out a certain answer. But because I knew that he peeped at the answers from the back, I snapped at him.

Me: You have the answer right? Show me your working now? Where is it?
Boy: EH, it disappeared.
Me: So you think you're very funny? The next time you do something like this, you can jolly well get out of my class. You're not welcomed here at all if you're not serious about your work. You understand?

My snap could be due to my lack of humour and most importantly, my lack of tolerance now. Because now I believe that an excellent teacher deserves excellent work! [Janice, you have to agree!] Now, I'm also a lot less emotionally attached to my students. A true professional does not see a rowdy and uncontrolled class as her fault but the students' fault. It's more of a survival technique really, how else then could you avoid depression if the students insist on being naughty?

I'm glad really and I really thank God that though I had an exhausting week, it went quite well. Despite my harshness towards my students, after school, they can still smile at me and say hi. Gestures like that are so appreciated cos they mean that they understand what I say and do in class even when I'm strict!
