I used to argue like my son.  He knows he is right and you are wrong.  He won’t give up until he wins.

I hope he gets over it.  It took me plenty long enough.

I’ve told him about this poem from my childhood:

Convince a man against his will,

He’s of the same opinion still.

People think if they repeat something enough times or talk long enough, you will finally smack your palm against your forehead and say, “Oh, now I understand!”

What you miss when you do this are other ideas and ways of looking at things.  When you can hold your own point of view and respect and listen to another point of view, life is much richer and abundant.
