So apparently, there's a fraternity on campus that's taking part in this event that they conveniently call "RUSH." (I think it's an acronym for something but I'm not sure). Anyway, I was unaware that it was an extra-curricular thing, so when I saw a guy today wearing a "RUSH" t-shirt I walked up to him and was all like "Hey man, nice shirt! I love Rush! What's your favorite album?" He looked at me funny and said "Who the hell is Rush?" Then he proceeded to explain it was a fraternity thing and I felt silly.
Then only a few hours later I forgot and said the same thing to a different guy wearing a RUSH shirt. I remembered what it was immediately after talking to him. I felt like a douche.
