Living Forward and Backward

"There is this difference," he said.  "You live forward looking for what might be coming.  Anxious you are to see round the bend and on down the road, while I live backward looking toward what was and wondering why it went so quickly by.  I've no need nor wish to see as you do.  Someday neither will you, but that is not today so I'll not pull you back -- as long as you don't try dragging me forward."
