Long time, no see...(5)

During the six years in A High School, no period was so exciting and enjoyable as the last 4 years. The chief House Master was my position, which gave me a very large field I could work in. Inside a given grade, Chief House Master was just like GOD! That position could give a teacher mighty power
for student guidance and counseling . It was almost up to him whether the school would expel a student who had done something wrong.
Five years had passed when an idea occurred to my mind that everything I did was something to make sure that I could play God. The idea terrified me a great deal. Students should never belong to me, because they are all God' image.
It was then when I made up my mind to change my job again. This time the reason is not to deepen my study but to be a real assistant for students' personality development.
