Leigh, first let me say such behavior should never be tolerated and the other students should never be exposed to such behavior. That said, we live in a time where mental health and awareness has become part of our daily lives as instructors. Some students act out improperly as such behavior is what they experience at home, they may not have role models to let them know such behavior is not appropriate. Handle each situation as its own, know each of your students and their personalities and always look out for the best interests of your students in your classroom and assist each one as best you can. Keep up the great work and I hope such situations are the exception and not the rule. James Jackson
