I was coughing so badly in my lesson that one of the assistants got me some water and said to me "have a rest!" but I drank a bit of water and carried on with the lesson.All they need is an excuse like that and they probably won't pay me.The show (class) must go on, I need the money!I find it funny that even the teachers at school who don't speak English seem to know the phrases "Sit down", "Have a rest" and "Class is over", some of them also know "Let's go" but I think whoever taught them their English was either always tired or very unimaginative!
