Fighting is just a part of life -- so knowing how to fight fair is crucial. To learn some vital tips,

• When you fight, keep your argument relevant. Don't bring up past arguments or gripes that have nothing to do with your current discussion
• Try to keep your voice down. You're much more efficient when you talk versus when you yell
• Be sure to have your argument in private, away from family members, children, friends, or co-workers
• Be direct and honest. Get whatever it is off your chest and deal with the issues at hand dead on. The person you are arguing with isn't a mind reader so don't let anything go left unsaid
• Listen to what your partner has to say just like you want him or her to listen to you
• Don't hit below the belt -- low blows could inevitably cause more damage than what was already done
• Be sure to own your feelings -- use "I" instead of placing blame on your partner
• Know when to offer up an olive branch. Fights shouldn't last forever. You're most likely fighting with someone you love and care about, so try to keep everything relative

As a personal rule of thumb, I never go to bed mad -- but do you all have any other tips you want to share?
