Although most of us are grown up and have a semi responsible head on our shoulders.. it takes very little to get caught up in the moment and do things we regret.
I'll leave these things to your own imagination, BUT,
I thought i'd just leave a quick reminder for those who are celebrating tonite, to enjoy themselves resonsibly, and if you're drinking, call up a cab if you have to get home, spend the nite where you are, or just be that sober guy/girl that'll remember all the embarassing things your drunken friends will be doing.
in summary!
Don't drink and drive, and enjoy yourself responsibly!
