Somebody once said there was a fine line between right and wrong.  That may be, but there is still a line.  There is a fine line between blue and green.  It's true, there is a line...it's yellow.  I imagine lines of separation in most everything, some quite miniscule, as lines go. 

I recognize a line between quitting and surrender.  If I quit; If I take the ball and go home, I'm out of the game.  In fact, it's unlikely the game will go on.  But, if I surrender the game continues and I'm still a player.  I like a little yellow with my blue and prefer to play the game.
