I always try to be polite to my pupils. I expect the same back from them too. Sometimes in a classroom scenario things get a bit sressful, you feel frazzled and you say something that you wish you hadn't. Sometimes the atmosphere is ever so calm but due to an inability to regulate the words coming out of your mouth you still say something utterly stupid.

I wanted a girl in my year eleven class to stop talking. I carefully chose my words, very slowly and deliberately. What happened next is best described as being a bit like when you're writing something and you want it to be really neat. You put so much effort into the presentation that your spelling goes horribly wrong and you put the same the same words in twice. What came out of my mouth was 'shut your mouth', which frankly wasn't what I was going for, even if my tone was calm and polite. I frantically apologised and went bright red.

I might as well have just told her to shut the fuck up, which in some cases is actually quite tempting.
