Such an idiot
I sat down at my laptop and put in a New Pornographers CD to listen to while I figure out what exams I'm missing. My headphones were on, but the music was really quiet. "Huh," I thought. I tried to turn up the system volume - no better. The WMP volume didn't help either. Stupid me - I had my headphones ON but I was playing the CD through my computer speakers. I'm sure the TA office appreciated hearing most of "Mass Romantic" while I figured that out.
