Waiting for the Train

Some days I spend a lot of time waiting for trains, some days I don't.  Metro has no idea what a schedule is or how to stick to one.  They may post a suggestion of a schedule online, but it is merely a suggestion.  The displays in the station give you some general idea of when a train might be coming, more or less, and maybe in the order they are posted.  When I was growing up my father told me, "never run after a street car or a woman, there will be another one along in a minute."  I now understand why my mother always turned blue when he said that, but he had a point.  I have learned to never run after a train, there will be another one along, sooner or later.  As for women, I never run after them.
