What does Heather ask of Melinda?

In Fourth Marking Period, Heather once again comes to Melinda’s door begging for help. She whines about the Marthas and says that they take advantage of her and do not appreciate her. They have asked her to decorate the Holiday Inn ballroom for prom, and she only has a few hours to do it. Heather asks Melinda if she knows anyone who can help. When Melinda does not respond, Heather assumes that she has volunteered for the job.
