Just stop for a moment. Have a look around and you'll see mobs of people rushing to get who knows where. They never seem to reach their destinations.
Nothing more than a non-stop parade of meandering souls coming and going. One lady isn't looking where she is going and jars me to the side. Another person passing in the opposite direction, bumps me back into the mass of cytoplasm.
Brownian motion at its best.
From the slightly elevated entrance, I can look pretty far down to the end of the main hallway. I feel like I am floating on a restless sea of bobbing heads.
