A study in how not to do it, probably.

A while ago I had a thought, today while out getting lunch I saw it in action.

With the advent of smaller and smaller technology, in particular for this example bluetooth phone headsets, I wondered whether people's opinions would change.

As the old saying goes, the first sign of madness is talking to yourself. I've often wondered with the more widespread use of the bluetooth headset, and it negating the necessity of having a phone on view, whether talking to oneself in the street would become more socially acceptable

On my way to the sandwich shop at lunch, there was one of the local care in the community guys (not sure the PC way of describing people with disabilities these days) wandering down the street, minding his own business, quite happily having a conversation with himself.

A bit further on, there's a woman, in business suite with attache case and a purposful stride, for all intents and purposes talking to herself and gesticulating as she's walking down the street. Granted on closer inspection you can see her headset tucked out the way under her hair, but still, if you weren't to know, how would you tell the difference?
