Agree to disagree.  This is very good advice.  It is the perfect example of opposites working together in your world of duality.  It is acknowledging the duality at play and that perhaps there is reason and purpose in this ongoing dance.  Why do you need to agree?  That is the question from which learning ensues.  Why do you need to agree?  If your answer comes with indignation as you insist, “Because I am right!” then there is yet more learning to be had.  First and foremost, learn not to take the drama and your role in it so seriously.  You are so very loved.
