On the subway to work this morning, the train started honking and slowing down. I looked out the window, and saw a group of workers in hard hats standing against the wall of the tunnel so the train could pass. I don't know what they were doing, but imagine if that were your job! The trains come by every 2 minutes during rush hour, so their work gets interrupted every 2 minutes, and they have to drop everything and get out of the way!
