CO at hall today. Its kind of hot. Indeed, its very hot compare to music room. Can't hear what we were playing at all. The environment was too noisy. Got called out for measuring size of new costume. Then I heard instructorZhng shouting. Didn't really catch what he was shouting or who he was scolding. Returned and realised that it was the badminton people he was shouting at. It wasn't quite common for him to be so angry, guessed the noise really irritated him. Still, I don't think he had the right to scold. In china, yes. In Singapore, maybe yes. In Evergreen, he is only in charge of CO. He shouldn't have scolded those badminton people. Hall belongs to everyone. Now he had blacken our CO reputation. Guessed it was done, can't be changed.  ¶ 7:44 PM
