Well it depends.. If he knows more about the subject, I'll let him have it.. If I know more, he'll let me have it. If it's equal (or neither knows crap!) we try to work together to resolve it. But usually one has more passion or knowledge about one thing so that's usually how it's split up. Very rarely do we fight it out about something. I do however let him win on stupid little things that I don't really care about and save my fights for the really big issues, which are few and far between.
