Yesterday walking back to the office after lunch, I was following a girl who was chattering away on her cellular phone using her wireless headset.

It occurred to me that for years on of the signs people looked for when evaluating your sanity was whether or not you talked to yourself in a conversational way, or appeared to be talking to an invisible companion.

Since the advent of the bluetooth headset and it’s popularity, this has become less and less of a tell.  How are you to know that the person standing next to you in the convenience store looking for a soda is really talking to an invisible companion, themselves, you, or someone on the phone?

Welcome to the world where talking to yourself for no apparent reason may cease to be thought of as mental instability!
