The Colby Outing Club is by far the most popular club on campus, but Colby Cares About Kids is also extremely active.
I am in the Chorale, the largest choral group on campus. One of the music professors conducts it and auditions its members - about 70 students, male and female. We go on tour (usually to Europe) every other year, and not to be biased or anything, but we are REALLY REALLY good. Buy one of our CDs if you don't believe me.
Whether you leave your door open depends on which dorm you live in. Most dorms, especially the smaller ones, are very social, and people leave their doors open for visitors whenever they are home.
There are two types of relationships at Colby: longterm relationships that start to resemble marriages and hook-ups. In the longterm scenario, you sleep over at your significant other's place most nights of the week and are (ideally) exclusive. Everyone knows that you two are a couple. These relationships frequently last until one person graduates or goes abroad. The hookups are self-explanatory. No one really "dates" at Colby because it is impossible. By the time you start "dating" someone, you already know them too well to go on a "get-to-know-you" date. Also, we can't really draw on the "nearby" schools for new blood because they are too far away, and oh, did I mention that it's cold outside? Take my advice, and get yourself one of those longterm relationships so that you have a bedwarmer.
I met my closest friends from living in a dorm with them or participating in the same extracurriculars as them Freshman year. I have met all my other friends since then through these initial friends.
Awake on a 2am on a Tuesday? There's no doubt about it - I am frantically doing homework (or wasting precious time filling out surveys on college life).
Doghead - drinking fest around St. Patty's Day
Loudness - the first and last weekend of every semester
Champagne on the Steps - seniors get drunk on the library steps the last day of class
Last weekend, I ushered at a play for the theater department (it's my work study job) and attended a show by a "Psychic." I also watched a movie with my friends. (It was not an exciting weekend - the weekend before that I held an Old Hollywood Glamour party in my room where everyone dressed up and drank [legally!] and danced.)
