Dear Lady Who Cut Me Off in the Carpool Lane,
Seriously? What is the matter with you? I was waiting in that line for nearly half an hour and you thought you would just sidle your way in? There's this unwritten rule about lines that says: Wait at the end when you arrive. Also, there's a rule about cutting people off that says: Don't cut off people you will see at tomorrow's PTA meeting.
Did it not dawn on you how easily I could find out who you are? It's not like you did this on the highway ... we were going to the same place. I saw your kids get into your minivan, as you were a mere five feet in front of me!
Also, you have stickers of your entire family on your back windshield (which already makes me dislike you), so it wasn't like I needed to be David Caruso to put the pieces together.
