When Seth told Anita, "Your plan for purr semester project is not going to work." she snapped back with, "I don't hear you coming up with anything better." When he asked Anita about the incident later, she explained that PMS (premenstrual syndrome) hormonal changes made her react more strongly than she really intended. Seth said, "No problem", but silently wondered if her menstrual cycle had made her cranky, or if she had a general tendency to be cranky, or if the offensive way he criticized her work was more a factor.
