Your voice changes into 'your teacher voice' and along with your voice, your tone and accent change too. You sound all prim and proper and well spoken- especially if you're reading out loud. And every word is enunciated as it should be and you say your t's and...

Then you leave the class.

You know that feeling when you're wearing a new bra and it's kinda restricting thing amd you finally get to take it off.

Ya. That's what happens.

Then my south african comes out. Then it's like "Ya, boss I don't know why you think I teach English. Hai, you mad. You don't know nothing."

That is literally the change in 1.5 seconds.

Also, my new favourite saying: "If you make a noise, I cannot pretend you do't exist! I really want to pretend that you do not exist right now."
