i think it depends how close you are. people like this will tend to not listen and try very hard to ignore someone who is telling them something they don't want to hear. if you sit them down and try to level with them as seriously as possible (preferrably in a private place) that may help. the situation is supposed to be a little uncomfortable for both of you, so that they may let down their guard and really talk to you. if this does not work, they may not feel close enough to you to be able to do this. give it time.

--who ya callin' smart alecky and stubborn? why you blankety blankety so and so things are gonna bve my way or not at all i know what's best for everyone, i want the world! HAHA HA HA HA HA I WILL RULE !!!!!!!-----

It depends on what kind of relationship you need to have with them and what you need to say. If this is someone you have to work with or live with a lot, you probably can't just flip them the bird and walk away to thunderous applause. If that's the case, there's no substitute for doing the difficult work of trying to understand them. To say they're "naturally stubborn and smart-alecky" is to oversimplify them quite a bit. Basically, you've formed a fixed opinion which doesn't have much room to allow that they're human. There's no room for compassion or understanding what the world looks like from their perspective. I don't doubt that your opinion has a factual basis, but its not the total story about this person -- the reason I know that is because no human being can be reduced to a 5-word synopsis. We're all complicated creatures with many different influences, conflicting ego structures, ideas of self and other, etc. Usually when someone has "ego trouble" and problems relating to others, its because they have a weak inner core of self-worth and confidence. This makes them feel isolated from others and frightened, and they try to compensate in some way -- unfortunately, the compensation strategy often is so obnoxious that it drives people away even more, leaving them more isolated, and so forth. Its a vicious circle. The amazing but little-known fact is that it only takes one person who really cares about them to help them unwind from this mess. That person could be you, if you're willing.

start by telling them how you feel about the way they act and if your willing to change that do that, also see if they're willing to change. (i'm sort of a stubborn smart-aleck myself.)

I always do my best to communicate and sometimes I have been successful.

I try to be as patient as possible.
