I honestly think there's something in the teenage brain that makes adults cellophane. I think that they just don't see us sometimes. They're so consumed in their own energy. I was traveling from the Charlotte airport with my baby recently. I had one big suitcase, a big bag with his carseat in it, and him in a stroller. And heaven help me, I parked where I had to get on a bus to get to the terminal. People were so helpful, and most of the helpful ones mentioned that they had kids of their own. So maybe the key to modern chivalry is empathy. Or, as someone else suggested, maybe the key is being below the Mason-Dixon line!
