Alone in a Crowd

I am noticing that if you look around any crowded area a significant percentage of folks are text messaging. I am sure if I took a sample of the population I could chart the probability of X people being on a cell phone.

To finish off an unbelievably challenging day I am having a HUGE pina colada and veg quesadilla at our local Mexican restaurant La Pinata. At least half the people at the bar are alone and texting. Obviously, this includes me too.

Is this cool factor? A way of ensuring you're not bothered or an illustration of the ultimate loneliness?
