Lifeboat Ethics

As with everyone else, it is time to make my college post. I'm having lots of fun, but am confused as to one minute point, when do I get to stop being nice. For the week of orientation, we're all supposed to be civil and shake hands with and introduce ourself to anyone that comes our way. Past that encounter, we may or may not continue to stay in touch. I've realized I really don't like meeting people this way, I feel like I've met enough people at this point that I can just hold back and get to know them better, but being friends with only 20 out of about 1500 seems rather closed minded.

I will continue to keep my door open and play loud music to draw people into my room, but which path do I persue outside of my room: being unnaturally peaceable just to write down names, or hoping to meet friends of friends in an effort to get to know the entire campus?
