Stupidity! Stupidity!
Mom and I went to Little Caesar's to get some pizza for supper. She wanted me to order it this time, and so she told me what to order, but since I was only partially paying attention, I ended up leaving the car and running (yes, running, because I normally run whenever I'm thinking) all the way to right in front of a woman who had just stepped out the door before I realized that I should've paid more attention to what to order, so I then ran back to the car to ask Mom about it without thinking to hold the door open for the woman or to look the slightest bit normal. D'OH!
