Please, I beg of you, stand to the right.

Have you ever been one of those people?
The ones running full speed through an airport terminal with a crazy look in their eye and some carry-on bags flying in the wind behind them?
Today, Ryan and I were those people. I was kinda laughing (in between huge gasps for air) knowing that as we sprinted along children were tugging on their mother's pant leg saying, "mommy, look at those people!"

Which brings me to the question... Why don't people know to stand to the right so that people like us can run past them on the left side of the moving walkways?
