The most important thing when it comes to the unavoidable (one's bound to encounter rebels when teaching teenagers, there is no escape from chaos - it marks us all) is to react immediately. Not for us Obama-like approach, no, we have to be swift and smooth and deal with the rebels changing them into the paragons of English students ;) Or at least try - because in order to change our students (or rather their attitude) we must try to understand them... and it's not easy, trying to understand people who don't understand themselves!

One of the most difficult tasks for me as a teacher is designing tests (and then test correction, I really hate it) - and the picture above explains why: it is virtually impossible to create a test everyone could find something they are good at.
