A week or so ago, I had an unfortunate accident on the bus. I hit my head on an over-head railing when the driver took the corner to sharply. 

Well long story short, after waiting a week with terrible headaches, I went to the emergency room and was informed that I had a concussion. 

No need to worry! I finally got a cat-scan after waiting in the ER for 7 1/2 hours. There is no bleeding or bruising and I am on the long road to complete recovery. 

To cheer me up, one of my roommates taped this to my door when I returned from the ER.
