One of my fave things to do when I have a longer commute is to catch up with folks on the phone. (Don't worry. I always use a hands-free headset.) That way when I finally reach home at the end of the day, I don't have to talk to anyone if I don't want to.
Over the last few weeks, one of my more common conversations is with BWB on the evening commute. See, we now basically have the same commute. And I often get on the road before she does. So I'll get the "How's the traffic tonight?" phone call. And then we discuss the route.
That happened last night. And traffic sucked hardcore. So I told her that I was taking my alternate route. Well, she decided to take the same one. And as I was describing where to make a turn, we suddenly realized that she had caught up to me and was directly behind me. And this was just as well. Because she had never been my secret route before and so I was able to lead the way.
