Boisterous behaviour

Last Thursday during my french class, l ran into my old classmate, Issac Ko, who transferred into my french class as his Fridays are not free these days due to CCA. He studies in River Valley High and is notorious for stirring up trouble during class. He has already gotten an official letter of complain from the school. Last year he even got in school suspension after numerous cases of outright defiance to a teacher. He might even get expelled if he continues to have this boisterous behavior. I hope none of my classmates will be like him
