I'm working in my (shared) office at school, trying desperately to get some stuff done before I either fall asleep or die of brain-overloading. So, every once in awhile, someone else with a key to the office comes in to study, or grab books, or get some food from the fridge. But, just now, one of the guys who studies in here a lot comes walking in, looks at me, and goes "Hi! I'm drunk!" Then he grabbed his stuff and stumbled out. Priceless.
I love it. I'm jealous as hell. But I love it.
