Arguments And "Winning"

When you don't have the same point of view as someone else, it doesn't mean they want to "argue" or "win" or convince you that they're "right".
Everything is not about winning and losing, everything is not a competition.
You can BOTH be right, or you can BOTH be wrong, or one of you can be right and one can be wrong, WHO CARES?
What's important is the actual information or solution, not WHO is "right". 
If that's the most important thing, then the solution will probably never be found, and the relationship with the person will probably just get ground up.
