Mr. Dung, my mathematics teacher, does seem to be by far the best teacher in my life for myriad reasons. First and foremost, he loves his job and has an in-depth knowledge of it too. He has an ability to make the subject that many students find incredibly abstract become easier through his enthusiam and passion for the mathematics as well as his loves of being a teacher. Sencondly, he offers us a number of valuable life lessons such as being couragous and open-minded. It is he that brings us out of our shells and gives us a great deal of advice whenever we have a difficulty. He makes me realize the importance of being open-hearted when interacting with others, trying to find something I like about everyone in order to create a pleasant experience for both sides. To sum up, I am grateful to him for all that he brings for my life.
