It's a mystery to me

I see this all the time while I'm driving into work in the morning: a woman on the phone, usually not a man, also driving to work, obviously engaged in the most engrossing conversation of the entire day.  Wait a second--it's like 7:30 in the morning.  What could you POSSIBLY have to talk about at 7:30 in the morning???  How are you even functioning well enough to drive amongst sleepy-eyed, barely-awake motorists who could hit you at any moment due to the joys of sleep deprivation?  I don't get it.  Is it me?  I mean, what is so important that you have to carry on this conversation first thing in the morning, while you're DRIVING, no less?  I just pray you don't shut down 76 East because you couldn't wait until, I don't know, lunchtime maybe, to hear about how Stacy and Bobby hooked up last week and he never called her back, and how Linda and Joe are getting a divorce, and how Donato is cheating on Antonia, all while you side-swipe the sleepy dude in the car next to you while you're trying to change lanes, because hey-how'd-my-exit-get-here-so-fast, causing a ten car pile-up.
