I teach them, play with them, but watch them growing up. I am always young when I was staying with them. I know there is not easy to be a teacher. You have to learn in order to teach. Without enough knowledges, you can never learn well. What is more, you have to be friends with your pupils and take good care of him. Only by this way can you be a good teacher and win respect from them. Though I am a student now, I will work as very hard to make my dream come true.
