Ever been standing in an elevator, and the annoying person's phone goes off. They read the message, and once they start to reply, your ears are filled with *click* *click* *click*. My hypothesis is that most people don't know how to tun that setting off. I mean, people can't be expected to know how to use the settings menu on their phones. Even worse: I have had people in some of my classes with iPads (eww) with the clicking enabled. They take notes all class with the constant clicking. Also bundled in this post: People who don't mute their computers when they turn them on in class. Countless times you hear the Windows Start-up sound, or the retro Mac sound. Understand your electronics please people.
