How much time can an argument really take up? Well if you think logically arguing is therapeutic to get feelings out, who wouldn't want to let someone have it here and there because the anger has built up. It feels good to release our feelings than keep them inside but most times an argument doesn't solve anything and either person cannot recall each others exact words. Therefore the argument wasn't too effective in letting that person know how your feeling. When two people argue they don't really listen and respond the yelling, they hear bits and pieces of what you say but are thinking of their next response back to you.
Try walking away, go for a walk, sit alone in your room, and then take a deep breath write what you would like to say down to organize it and come back and either hand them the paper to read or talk your organized thoughts out.
Think about it, if you hand someone a note written with your thoughts they are listening because they have to read and are quiet when reading. They can then respond to you and you have gotten all your feelings out and know they have all been read. If you can talk it out you are actually solving some issues, if you are yelling its just one big competition of who can anger the other person more with their nasty remarks. Sure it feels like you have won but what are you winning a medal of sarcasm, a gold medal for having the last word. Come on everyone if we can't get along then we have all really lost. Think of winning in your discussions as being the champion of solving the mystery, how to make the other person smile first. So be the one to win ending the argument, in the end we only fight because we care and want that other persons understanding.
