This person is looking for extra attention outside of class, and i think the instructors lack of immediate response is telling her they are not going to respond to her manipulations.
She may be used to throwing tantrums and getting her way. Thats probably part of why she is in class! She is there to learn this exact lesson. Unfortunately, you bore the brunt of it, which is not your place - youre not getting paid for it, the teachers are. Consider it extra credit work on your part?!
