In this purely hypothetical scenario (cough, cough), say I was driving home from work and listening to the news on the radio. I was anticipating an exciting story (something like "Army of Cyborg Dachshunds Intervenes in Libya") but in the meantime the radio insisted on airing news items I definitely did not want to listen to ("Third Graders' Reactions To The Latest Episode of Dancing With The Stars"; "YouTube Sensation Is More Important Than War In Afghanistan"; "That Hobby You Like So Much? What Is It, Board Games? Geocaching? Yeah, That Gives You Cancer"). To combat this menace, I decided to listen to the newest awesome CD* I own, Sigh No More by Mumford and Sons.
Now, to switch from FM Radio to CD, I have to press the CD button. However, every single time I do so, I instead press the "Band" button, which cycles through the AM radio and the stock satellite station that I refuse to subscribe to. This in and of itself isn't so bad, but in the course of trying to catch the awesome story, I switched back and forth about four times to hear a snippet of a story I didn't want to hear ("Environmentalist Thinks He Is The First Person To Realize Oil Companies Are Bad People"). Each of those four times I managed to do the exact same wrong thing.
And I have been doing this for maybe four straight weeks. I don't think I've pressed the right button once.
I think somehow my brain has trained itself to do this. Now that I've done it the same (wrong) way so many times, my brain thinks it's the right way. I suspect the only cure is more caffeine.
*Yes, I still purchase CDs.
