Stupid, stupid, me.

Never ever ever drink and party BEFORE the last final. Never. It makes no sense. Even if you are completely prepared. Even if it's your favorite subject. Even if a good draft of your paper is already done, and is resting safely in the hands of a trusty proofreader. Of if you must party, don't drink. Or if you must drink, don't drink a lot. Or if you must drink a lot, don't do it in the company of Russians.

I will never learn.
