This really just seems like a culture-clash in action. I don't know what the general sentiment is at NYU, but the university I attended had a very strong "shopping week" culture. It was quite common, and quite accepted, to shop three classes simultaneously, spending 20-30 minutes at each one and leaving or joining midway through the class. In that context, xxxx's only real faux pas was sending the email, which was perhaps a hair self-important. I'd love to hear from an NYU student what the social mores there are.
