Parent asks teacher what he knows about another student whom she alleges is harassing her child

A teacher at a middle school sees a male student being verbally abusive to a female student in the hallway. He immediately notifies the principal. The next morning, the mother of the female student involved in the incident appears at school and asks to speak to the teacher. She explains that the male student and her daughter have been going out for four months and that she is concerned because the boy has become very controlling toward her daughter, telling her what she should wear and instructing her not to spend time with her friends.
