Reasons why I am an Idiot, #1

I was almost on time to class this morning. Almost. I left the apartment on time for the first time in several weeks. The sun was shining, the birds were singing. And then I forgot(?) to get off the bus at the right stop.

Disclaimer: Based on my calculations, this is actually the 642^nd reason why I am an idiot. However, as this is the first documented reason, I'll start with number 1. Feel free to comment with successive reasons.
