I Am a Moron

The combination locks on the inner stairwell doors of my office building were changed two weeks ago. Our building manager put messages reminding us of this on hot pink Post-It notes above each doorknob and keypad. Every day I muscle my way up the stairs, see the note, and say to myself, "Duh. We all know the combination has changed. When are they going to remove those notes?" And then I promptly enter in the old combination.
