Prediction

Today our team went on a quick afternoon outing together to the Ferry Building.

10 or 12 of us walked in rows of two or three in columns of three or so, and I trailed at the back.

My eye caught a folded piece of paper in the back left pocket of a friend walking ahead.

 "I wonder if Mac is worried that that piece of paper in his back pocket will fall out?" I said to my row.

Minutes later I notice Jim to my left kneel to pick up a folded piece of paper from the ground.
