"If you board the wrong train, it is no use running along the corridor in the other direction."  Dietrich Bonhoeffer

I tried, believe me, but it was just the wrong train for me.  That doesn't mean no one belongs on that train, but it is time for me to get off.  The direction it is headed doesn't fit into the journey I am on at this time in my life.  And that doesn't mean I can never take a train trip again, but there aren't any tracks laid where I am going right now, and a train is of no use on a footpath.
