My phone has a button on the side which cannot be disabled and which makes my phone take a picture. It then makes a very loud shutter noise which cannot be disabled that notifies everyone in earshot that a photo has just been taken.
At work I have my iPod on and can’t hear the sound my phone makes when something else in my pocket, that same iPod, pushes down the button. I can hear my boss, when he taps on my shoulder and I take my headphones off, telling me that I have just taken at least two dozen pictures of the inside of my pants, and could I please stop.
Thank you, technology!
