Drivingdad, I’m still confused. Lisa’s statement that she had to study all the time is what the vast majority of students attending Vassar and every elite college avow.
And her comment that she didn’t do anything was made during an informal discussion and was obviously hyperbole. The Miscellany News interview noted that Lisa was a Mug Rat. I.e., a student who spends an inordinate amount of time at Matthew’s Mug, the central night spot and liquor dispensary for Vassar students.
How you came to conclusion that Lisa spent all her time in her room is beyond my comprehension.
