Then go to a sports bar DT!!!
You're young. Get out and have fun while you can! There's plenty of time for full time seriousness later in life, if you so choose.
Join the waterski club at Cal. Those guys are a hoot! And you'll be surprised at the broad range of people you will meet.
Enjoy your studies, but enjoy the young life!
P.s. I'm still waiting for you to bring me a Tia's burrito.
