So your RA, who claims she "likes to party as much as you" and "isn't here to ruin your fun," has lined everyone up according to their birthdays because obviously that's how you get to know people. You strike up a conversation with the person who's also born in February. Enjoy that conversation with your new best friend, as they'll only be your best friend until Thursday when you meet someone who shares an affinity toward Bob Marley greatest hits albums*. You are not best friends with this person. You will not be best friends with the Bob Marley fan.
*Sidenote: Don't let anyone tell you Bob Marley's "Legend" is one of the greatest albums of all time. It is a collection. It's like saying the best variety of Chex is Chex Mix. Sorry if that analogy is too good.
During your junior year, a frat will throw a beach themed party in which everyone will be hammered and making out while wearing next to nothing, and the first thought that will enter your now-jaded mind will be "I bet it will be crowded and I'll sweat a lot." Then you will go to an off-campus party where you'll sit on a couch, eating frozen pizza and talking about how great it was when you went to beach-themed parties just two years earlier. In the corner, there will be two guys. One will say to the other "Sorry, I thought hanging out at an upperclassman, off-campus party would be cooler. Sorry we didn't go to Beachcombers Blast." Those two people will never hang out again.
You as a Freshman: "Oh my God he does Bill Cosby impressions!"
You as a Sophomore: "Oh my God he does Bill Cosby impressions."
Notice the difference? You will.
I'm not saying you won't reconnect later in college, but there's a good chance that despite attending every party with this person during the first week, your friendship will not rise above any of the following issues (which are bound to come up):
That first week will undoubtedly be the best week of your life. Enjoy.
