You step in water after you put your socks on
You slice your tongue licking an envelope
You find that important receipt you were looking for. It is in an unopenable little compact ball in the clothes dryer.
You set your alarm for pm instead of am
You discover a piece of parsley on your front teeth after you've talked with several people.
You realize you stepped in dog poop outside after you've already walked across your living room floor.
You're yelling and giving rude gestures at at the driver in front of you because he is sitting at a green light - then you realize he was sitting there because an emergency vehicle is coming through the intersection.
