Your first year in college is usually spent trying to know as much people as you can and be come friends with them., It is the time when you build up your connections and your social groups. I myself have experienced this and I can say that I didn't do pretty welll when it comes to the get to know a lot part. I have a number of friends, but not enough connections. For me, having a lot of connections is important in college. You will have many information sources.
The idea of your university that freshmen move in to the university hall first than the higher years is great! This is a great opportuniyy to make friends with most freshmen in your university. It is chance for everyone to know people who would like to be friends with. And the carnival sort of party is even better! You don't only get to befriend other freshmen like you, but you also have the chance to bond with them right away! I bet it also made you forget that you are tired already. I wish my university also have this kind of welcoming party. I can imagine how fun it was! Enjoy college :-)
