In this case, actually, I was running late this morning and the subway is experiencing delays due to a disabled train. So now I'm really really late which makes me so stressed out. The same thing goes for traffic though, and that's probably more applicable to my (tiny) blog audience. It seems like when you're late you always miss the lights, get cut off, or get stuck behind someone who goes 2mph through the toll booth. It's probably just a heightened awareness of these things, as they likely happen with the same frequency when you're not in a rush, but it still seems like the world is personally attacking you.
