How can you smartly tell someone that they are repeating exactly the same thing that you told them before?

Say, "Oh, I didn't think you were listening when I told you that the other day. I'm very flattered that you value my opinions so much."

Consider it flattering and move on. You know where the great info came from. Unless this is somehow going to limit your getting a head on the job. Then I'd answer everything in email, that way it's documented.

For example... the annoying person asks you something. Tell them, I"ll get back to ya, I'm in the middle of something. Then flip the response in an email. Come review time, you can substantiate to the people that matter what a value you are.

The real problem with such people is that they are dim and they make up for their lack of intelligence by "parroting". But the plus side is if you stop feeding him material he will get it from somewhere else and feed it to you. So now you know whats what. The situation is absolutely hopeless. There is nothing that can be done to change it.I once had a friend like that and after five years of talking we had to part company.

I just say nothing. They usually are people who are of no substance and create, they think their selves through all the things they hear and see that they think are good. Just let them go on feeling that they are and sooner or later they will figure out that they aren't and will need to find out what they feel,think,like and know and then they'll be an individual with their own substance. Have a sister the same way,so I'm speaking from experience. Including me there are 4 girls in my family and she has collected the same things that each of us as individuals ourselves have collected. She does exactly like your coworker. She is now finally starting to exhibit singes of her own individuality.

You could try providing her with misinformation to repeat.

When someone tells her the information is not accurate,

she will most likely want you to take the blame for the misinformation; perhaps even confronting you. That is when you politely point out that she is now wanting to give you the credit yet didn't offer that when the information made her look good, when it was accurate. Always keep a smile when you're talking with her!

Eventually, she'll realize her behavior.

I often tell the same story more than once simply because I cannot remember that I have told it before, or because I can't remember that I have already told it to that person. It's not intended to be annoying. If someone starts to tell you something you already know, you can always say something like, "I know, isn't it incredible?"

i had an acquaintance like that, She's lonely, wants to be excepted, and un-original. You have to know that, and consider it a compliment. Move on, and forget about her lack of originality.

More likely than not she'll never change. Try not to talk around her, and un-associate yourself from her. She'll get the picture, and then find another person to copy. Sorry if my words don't make mush seance.

You could either good naturedly say, "I'm the one who told you that!" or else "I know. Do you remember I was talking about the day other day with you?"

Then, too, there's always the VERY good natured, kind-of-joking, "Hey, Susie. You're always telling me stuff I already told you. Am I that forgettable?"

Just point at the person and say, got a mocking bird in here.

I'm glad that you took my advice and . . . (then you'd state what your coworker did that you had said)
