Emily looked at the girls on the podium. They cleaned the blackboard, tidied up the podium, and tossed the trash. When they came back, they arranged the broom and other cleaning tools neatly. The class was about to begin, there were still people playing games and chatting in the back of the classroom. Jenny frowned and said, "Be quiet."
At first, the others didn't think much of it. After many times, they all looked at Jenny curiously. They couldn't figure out why Jenny suddenly changed. Not only did Jenny take the initiative to clean up, but she also supervised others to prevent them from chatting and playing games in class.
Jenny thought about it for the whole night and felt that what Emily needed her to do was probably to maintain a quiet environment for Emily's study. No wonder why Jenny thought like this. After all, everybody in this class believed that only a few people in the front row came to class, and the others came to entertain.
