The assumption that partying is something important that needs to be preserved.
Look, I'm not coming at this from a culture war perspective. I'm speaking from my own experience here: if I could go back and talk to my 17 year old self in the first week of school all these decades later, I'd ask about all the parties I was thinking of attending, and say, "Yeah, none of those matter. Feel free to skip, oh.., every one, from now until graduation."
Connections? Didn't make any that mattered. Romances? Zero. Friendships? Basically they were as strong as they needed to be from daily conversations.
What was really valuable and unique were the classes, though I had a hard time seeing that then.
But people here seem to disagree - and I don't think it's because they're all in college either. They really find they have value. Sadly, they did not for me.
