I am an Idiot

I decided over the weekend that I would make my way over to Starbucks so that I could keep up with Steve Jobs' Keynote today. I did the math in my head 20 times today and made sure I knew exactly when it started my time. Then tonight, I did the math again and decided that I would wait a half hour so that I would come in 30 minutes in to it and get to catch up and catch the end of it as it went on.

Now, I am at Starbucks and realizing that it doesn't start for another hour and a half. And I am quickly realizing that my math was done completely wrong.
