Moving through a crowd.
I was standing in a line waiting to board a Southwest flight last week and was amazed by a little man. Little man went to the front of the line, realized he went to the wrong place, then began to make his way back weaving effortlessly through the crowd waiting to board. It was like watching water run through a crack, he was the only one moving and everyone else remained still. I was in awe. If the BIG man tried the same thing it's comparable to a BIG rig going the wrong way, eventually it's going to get ugly and someone is probably going to get hurt.
