There's a game I like to play when I walk around downtown. It's called "Crazy guy of cell phone user" and it goes something like this. Let's say you're waiting at the bus stop and you hear someone talking out loud with no one in sight, making wild hand gestures. Is this a crazy person or is it just someone making a telephone call?
It isn't as easy as you might think. Bluetooth earpieces can slip unnoticed around an ear and disappear completely if the person has anything but a very short hair style. And you can't always judge by clothing because even successful professionals can dress down quite a bit.
Here's a hint for the rest of you. If you see me walking down the street, I can almost guarantee that you should put me in the "crazy person" category. I know that this is the Mobile Duo site, but really I only carry my phone part of the time and even then there's a good chance the batteries are dead.
I will, howver, often walk down the streets singing out random pieces of the current song stuck in my head. Usually I'll look around a bit to see if there is anyone within half a block or so around me. But even if there are people nearby I might just keep singing anyway, only at a lower volume and without moving my mouth as much.
