Dear Jerry,
I heard of your thing, I am sorry to hear that news. But don't be upset, cheer up and make some changes to let your teacher and students like you more.
First, I think you should be a little quiet and be a good listener. You can't be as naught as before, if you are always naught and don't look after results of your behaviour, you will make more troubles to get your teacher angry. Secondly, try to change a way to say your ideas, sometimes your way of expression is not very good, so that your teacher misunderstand you. So please pay attention the thses little things, you will be better then.
