difficulty agreeing to disagree

It has been my experience that men often have issues with leaving a disagreement unresolved.  Now, let me state up front that I am NOT talking about arguments between the sexes ... they usually go one of two ways ... ignored or accompanied by ranting & raving.  I AM referring to those little things in life that aren't important enough to take a stand on.  There is no right or wrong.  There is simply two opinions.  I'm ok with that. (and not in a "I know I'm right, so I'm not going to argue with you" way) It's more of an "I just don't care enough to carry on a long discussion, I don't anticipate being swayed, & I'm tired of scratching my head over it" angle!  Try as I might to suggest that we let it lie as just one of those things that we feel differently about ... the Capt isn't leaning in the same direction.  THAT, in itself, put us in the same agree to disagree box (as I see it)  I think this is a Venus - Mars thing.  These days, my head says "whatever" ... while I smile politely and TRY to drop the subject.  The Capt, in the meantime is dissecting the conversation to find reason within it.  HA- left brained or what?!!  Such a foolish waste of time.  HOWEVER ... it does, occasionally lead us to the point where I tell him he's probably right (saying the "p" word as sincerely as I can).  Afterall, it was only a conversation, and I was done with it!
