Recently, as I sat on the Northeast corridor train, the ticket-taker informed us that we would be delayed 15 minutes. As I thought about the impact on my day, a flutter of activity rippled through the cabin. Passengers called bosses, colleagues, wives and customers spreading the news. What was interesting was that the relayed news was different: some people doubled the time, others bumped it up to solid hour and, shockingly, no one made it shorter.
