People are passionate about everything!
Student government is fairly popular here, as are the various cultural groups on campus who host lectures, parties, and dinners. Sometimes it's hard to dedicate time to a student group when you have so much academic work on your plate, but somehow people manage to do it. I'm involved with theater on campus, and love how Wellesley supports the arts (like almost everything else). Not many people attend athletic events, but crew and tennis are very popular/well respected. The community system that is started from the moment you get at Wellesley is the best way to make friends, and the residential life is amazing (both really supportive and not too in-your-face). Many students have boyfriends from schools nearby, and you can see them dotted all over campus on the weekends. If i'm awake at 2am on a Tuesday, I am either studying or procrastinating studying, and I don't know too many people who would be doing otherwise. Last weekend I met up with friends from high school who go to other colleges in the area for dinner. Then I hopped on a bus and went to a final club at Harvard (a similar institution to fraternities), met up with my Wellesley friends, and returned to campus for a quiet night of peace! There are very few well-attended events on campus on the weekends, but the cultural shows tend to garner population and the few parties the societies (similar to sororities) have are also fairly well-attended.
