"What, did you go to the bathroom too?" Lin Jia Bao sneered. He then turned to the rest of the class and shouted angrily, "What about everyone else? Did not a single one of you see anything? Did you all go to the damned bathroom?"
"Hey, who do you think you are, acting so high and mighty? What gives you the right to question us like that? So what if we did see something and just don't feel like telling you?" Chen Zhuang shot to his feet. He was clearly much taller than Lin Jia Bao, and true to his name, he was built strong, making him all the more intimidating.
