Whine and Cheese

I've run into many people like the one you described, especially in NYC. I'd often flash back to Lily Tomlin's monologue about taking all the people who talk to themselves and pairing them up so at least they look as if they're having an actual conversation. Of course, this being the city, the scenario was often ruined when I realized they were wearing an ear-piece with a mic attached, thus ruining the illusion of a true dissociative disorder.

'Tis the season to be jolly, fa-la-la-la-la-de-f@cking-da!
