Yea. I'm a college student again, this is college life, can't change college, have to adapt. I can intellectualize and say "it's too bad we have to drink to change ourselves into someone who can be open and have fun"...but what does that change at the end of the day? Not a damn thing.

"Shut-in", is that code for married :P? Seriously though, different ages, different social context. Hopefully you're not trance-raving in in Roppongi :) That would be a bad call.
