How?

Today Ms. Krisbina told us to decide what we want to present and tell her. I've decided to present music because music can change people feeling. The main problem is Ms. Krisbina want us to wear formal dress. I don't have any kind of formal dress because I didn't like formal dress. While in the class, I felt so cool because the air-conditioner was locate upside my seat. I hope that the next class will be different. How different? I'm going to turn off the air-conditioner.
