Many years being a teacher, I never feel tired of my job.
My classroom is filled with laughter and sound of loud reading, sometimes even shouts and yells from them; for this is not only a class of mine, but also theirs—their paradise where they will enjoyably breath in knowledge.
I set a principle for them: they MUST speak English in class. No bargain. I know sometimes they may make mistakes, and every time I will stretch out my helping hand.
Then very soon they graduate. Occasionally they return to see me with some presents—I am requested to solve some language problems for them. Yes, I help them out cheerfully, like I have done many times before. I call this my “post-sale service”, because I know, once being their teacher, I have to work for them all my life.
