If you’re like me, you enjoy people-watching at the airport, especially in line for the security check point. Taking sweaters off, putting sweaters on -- digging for loose change or forfeiting a toothpaste tube that's dangerously large buried at the bottoms of their carry-ons. I never know the travelers in line, but it's amazing how much you can absorb just by the looks on their faces.

That guy who has gone back and forth through the metal detector four times but is still smiling. Or the lady to his left who seems to have a fear of flying. She's anxious, sweating, and probably hoping the TSA agent finds some excuse to keep her on the ground.
