Keisha, a new student is your group, has been disrupting the group during homework help by making rude sounds and repeatedly getting out of her seat to bother other students. When you speak to Keisha about her behavior she is rude and disrespectful towards you. Today, while your back was turned, she knocked over your supply box. She says it was an accident, but two other students who witnessed the incident say that she did it on purpose.

How will you best handle the situation?
