platform in the classroom and give lessons to lovely boys
and girls . 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

respect from them . Though I am a student now , I will
work as very hard to make my dream come true .
