This sounds like a strange questions but how do you deal with someone who lives with you (no separate rooms), stays at home all day (except for a night job), and is sometimes fun to talk to until the "know-it-all" kicks in. If they know ANYTHING about something, they treat you like a fool and say they know all about it. And if you have a hobbie they originally know nothing about they research, read 2 paragraphs about it, and say things about it, as if they're an expert!

Frankly have have told her, I'd rather not talk about it if she's going to be that way, and I've tried to hear it out to the end, but she says, oh, you just feel inferior is all, and there IS NO end to the blabber unless you leave or just yell shut up please!

How can I get her to stop! I have tried leaving the house, only to come back to it. I have tried being nice, and mean. I have tried changing the subject, but then she makes it all about here again. AAARRGGHH! Please help me! :.(

Try listening to your IPod. It will drown out her voice, plus you'll have music. Sooner or later she'll get the message.

The funny thing about that is I have done that and she STILL keeps talking! I literally won't respond for an hour as she goes on about how much she knows, and has done! I thinks she really that dumb and determined!

You can't change her behavior, the only thing you can change is your reaction to it.

So stop expecting to have a reasonable conversation with her and just talk to her about the washing, or cleaning the toilet, the weather, whatever.

She won't ever not make it about her - you can't make her stop. All you can do is change your response and get over being annoyed by it. It's useless trying to control her - you can't!

When she starts pontificating, just go 'blah, blah, blah' in your head. Otherwise, find a new room mate.

Gemini is right! Tune her out and if that doesn't work, find a new room mate.

Make your next hobby the study of narcissm?

Now that would be a good one! Tell her you are studying narcissm, and when she starts to tell you all about it, tell her it sounds familiar!

The best way to deal with difficult people is to tune them out.

I'd go with the iPod, and walk right out. And I'd also visualize, to myself, punching her in the face. That would certainly make me smile. Maybe sit and laugh histerically the whole time. :) She'll be confused.

Thanks so much! Maybe these will work!

Don't tell her anything.

What your studying,what your new hobby is etc. etc...

I think she is the one with the inferiority complex, always having to speak above everyone else, always having to be the number one at what ever she does.

No matter how you respond to this sort of behaviour, she will always be the same.

The best thing to do is just talk about every day things, when the attention seeking mode cuts in, just say calmly " yeh what ever", and continue with what you were doing.

If you keep this up for a while eventually she will realise that the reaction, she loves to see from you is not forth coming,hopefully she will give in.

OMG - I know someone just like this. She even talks to me as an expert - about me! What I do is just say, "Karen, I know you probably have read all about this but I want to learn about it on my own without your input this time." If that doesn't shut her up, I like the IPOD idea... teens have been successfully using them to ignore their families for a long time now!
