They are usually at heart unsure of their own worth, and so need to establish dominance by having the last word. It is like the final stroke of a sword in a battle.

Exactly - Win. But it comes down to something deeper: pride. "If I get the last word in, I win the argument." Whoever gets the last word doesn't get argued against - not in that conversation, anyway. It will also leave them with the feeling of 'being right'.

Simply because its so tempting. I always want to get the last word. I dont know what you would call it but knowing when to lay off is useful. People start saying things about me though and I feel the need to defend myself and I think that should be natural of anybody. At the same time though its good to see if im actually wrong or not. Humans really aren't that much more advanced than animals in emotions. Words and Science and creativity sure, but we still let our emotions control us most of the time. Anybody can deny this but I will call them a liar. No offense to you liars out there.

It's a EGO thing - That will come back and haunt Them in the end and that I know for a fact - I've watched my sisters go through that - and they truly deserve it - Buy leaving me out me out of eveything " My Fathers Will and thought I was to dumb tio undersrand -- Wrong They were and are

I think it's more need than want. People like me for instance, just can't control themselves. We always want to make certain that the other party understands just what their point is. I do it because I'm trying to be helpful, but, it is annoying I realize so I really try to let things go. I'm getting much better at it, too. Just not with my husband for some reason. lol This time I'm giving you a makeup travel type bag in lieu of points.

I think it is just the almost overwhelming need to "come out on top". To make sure that their point is the only one and to have the final say on the subject. I make sure that my hubby always has the last word... just as long as it's "yes dear". J/K ;-)

It arises from early childhood or past misunderstandings where one feels they were not able to get their point across to a degree which allowed their words to be fully accepted, understood and/or agreed to. This results in the person then desiring to have a sense of control over future conversations, debates or arguments and makes it very difficult for them to 'let it go' until they are able to reach, what they consider to be, a satisfactory closure point.

Control....the need to end things when they think it's over.

Sometimes it is because they are overweight and have addictions.

perhaps they are not seeking answers, but victories.

Individual power & self pride!

Habits can be annoying, irritating, and even sometimes beneficial; but not all habits are bad some of them might even benefit us. Bad habits can be corrected; the best time to correct a bad habit is immediately, before it becomes established. So, bad habits are best prevented from developing in childhood. Did you know that scientific research has shown that our nasal mucous is beneficial to our immunity system? I’m saying that I would actually expect you to eat your boogers, but children have been known to do this once they hit a certain age. Do you think that it’s an accident or coincidental that develop a taste for them or is it something more? Habits are those routine things that we do every day, often without thinking twice about them. Brushing your teeth in the morning; putting on your seatbelt when you get in a car, and grabbing your purse or wallet before you head out the door are all habits. After awhile they become routine. Sometimes we develop bad habit, these than become a negative impact on our lives, and even your feelings about yourself, even your health and relationships can be affected by bad habits. Bad habits may give people the wrong idea about you, or they may even lead to people avoiding you in certain situations it depends on the severity of the habit. Last word people and the need to finish the sentence. Some people have a habit of must having to get the last word in. It is a matter of control sometimes but mostly it is the need to end things when they think it's over. It arises from early childhood or past misunderstandings where one feels they were not able to get their point across to a degree which allowed their words to be fully accepted, understood and/or agreed to. This often leads to problems within a marriage and the spouse will usually feel like he or she can never speak or be heard. This habit can be overcome the person with the last word issue needs to try and listen more and not be so anxious. He or she just needs to be patient and wait. Let the other person try to have the last word once in awhile this will usually help many issues in the end. It’s like having the feeling of desire, as if they have the best way to finish the conversation. It’s like as if what they say will be the best way to close a sentence. In some cases the person just really needs to be heard and get what is on his or her mind out. It’s like a feeling of “if I don’t say it know I may explode” an overwhelming feeling of want let it out. These habits and many others can be resolved. Habits are bad, but not impossible to overcome and deal with. We just need to be aware of the habit accept it and try to understand what is really going on. In conclusion I feel that some of the habits that we have we do on a daily basis; we have turned them into our day to day routine. Most of the time we aren’t even aware we are doing them, but if we take just a little time out of daily routine and pay attention or exam the habit we might find a resolution. If nothing else we will definitely have a better understanding of ourselves and habits we have formed, and maybe even why we do them. I’m not asking you to change just to take a look at yourself and see if these apply to you. Maybe we won’t like what we see, but maybe we can change just a little. And just maybe the people we surround ourselves with will like us a little bit more.

Some people think that means they "won" something.
