My position on the "What time is it? SHOWTIME!" kids is well documented at this point, so I won't get into it here, but when they got onto my car during this afternoon's rush hour commute, I may have uttered a curse and walked between the cars to escape them, laws be damned.
Watching them silently finish their shakedown of my former car through the windows, I realized my error: they were making their way toward the back of the train. They were following me!
I saw them, and they saw me, knew where I was going and why, and one of the kids, with a deferential nod, graciously held the door to let me pass back into the car I'd just left, as they began their act once again.
