yesterday went back to school for the 20th anniversary: COL(Colours of Loyang VI). just sit there watch the concert and talk only. one of the day our school discipline master say when we are sitting in the hall we cannot talk and use the phone. if we talk he or the teachers will chase us out of the hall and if we use the phone he will confiscate. but yesterday when concert start, i did talk but none of them chase me and my friends out.
