Argument= an effort to establish belief by a course reasoning. Both the opening speech of the counsel representing one party and the answer of his opponent representing the other party are called arguments (Reader's Digest, Family Legal Guide, 1981).
Argue Smarter= Pick your battles! Drop the insignificant issues and laugh them off if you have to. Get to the root of the matter; however, the problem is usually not what is being presented (the perfected lie)...lol..
Nip it in the bud and if the other party doesn't want to take responsibility for what they contributed, MOVE ON! Easy to say, hard to do, but it works if you choose to make it work for "YOU."
Maintain and meet the bigger goals/tasks at hand. Sometimes agreeing to postpone the discussion when things cool off keeps it from escalating further. When you have the conversation later, if you choose to at all, it may be a little easier to confront, http://allyou.com
