You can tell you're in a 1000 level class when: Everyone around you is talking about how drunk they got at a fraternity they don't belong to over the weekend. Then they start making up lies about which girls they hooked up with. This eventually leads to a bunch of name calling and the calling of bluffs. Overall it was amusing, but it got old after a while when I realized every single person around me is 3-4 years younger than I am.
