Short and simple, if you are wearing one and you are not on the phone...you are a tool!
Just stop! I do not care how much money you think you make or how important you think you are, you are a total jackass if you think you look cool walking around with a HEARING AID dangling off your ear. In fact, when you are talking on one of these things in public, keep in mind that there are other people around you that do not care about your discussion with the other party. Keep the conversation to yourself, you are not Jerry Maguire. This goes for all public mobile phone usage, keep your conversation private.
That is all, I will call you later. Bye (click).
