Airplane arm rests: Either put them down before your seat mate arrives or not at all. Because if you do forget to put down the arm rest before your seat mate gets there and then you'd like to put your arm rest down, you will (if you're anything like me) be hesitant to do so in fear of said seat mate thinking there's something wrong with them that requires a divider between them and you.
Vibrating phones: Most annoying when you hear the vibration but then upon checking the phone to see why there was vibration there is nothing. Leaving you to wonder if it vibrated at all or if you now just hear random vibrating sounds.
Applying makeup while driving: STOP! For the love of all that is holy, please. just. stop.
Vacations: Why can't they hurry up?!
(I have this overwhelming desire to make my next thought start with an "A." Do you see the pattern, too? Must resist.)
The truth: I have been writing this post since last Thursday and I have kept pushing back the posting date in hopes of coming up with another "A" thought to complete the pattern. Sad. Neurotic. Pathetic.
