In my work place which is a private affter school, I saw so many conflict. I remembered that one day: it was my turn to watch the student if they were disciplined on the class. Our princepal called me to sent out the 5 student who get out of line, because he can exactness know if student were getting out of line through the carema.  Immediatetly, I went to that class room  to sent 5student out. There is a rule the student who get out of line can not in class until they finish copying 500 word.
