The Undergrad-Grad standoff continues

Harvard law student (graduate? they're on semesters, right?) Amber Taylor, writing on the worst things about her city:

"The city in which I live (for the next two weeks) is Cambridge. It is cold for eight months of the year, hands out parking tickets like candy, my local branch library is closed, it has tons of homeless people, and it's stuffed to the gills with Harvard undergraduates."

Wait, what? I know, I know, it's not the place of a UChicago undergrad to stick up for Harvard kids, but why is a Harvard law student any better than a Harvard college student? Why would a population of studious kids who mostly behave themselves and who are probably, some of them at least, quite interesting, be so annoying to have around?
