Repeating someone's opinion word for word and taking it on as your own?

With the option of that certain someone having a weak personality or some serious self-esteem issues ruled out, I must raise another option, which comes high on the probability score; is it possible he was mocking you? You see, I'm troubled by the fact he reproduced also the intonation... This is uncommon when someone just agrees with you, by repeating your statement word for word... Usually the intonation differs, being consistent with the speech pattern of the person reproducing it... In short, the words are adopted, but the tone is original -- this is what determines us to rationalize (i.e. interpret the messages from our subconscious mind) that our words "were taken as our own" -- the difference in intonation.

Remember from early childhood, when we used to immitate someone -- we spoke not only using the same words, but also the same intonations, even posture, gestures etc. The main purpose was either to annoy or to mock that person.

When you hear someones opinion or view on something that you know nothing about, but you hear it over and over again you instinctively think that it is just as what it is said to be. That is our minds way of subconsciously dealing with fears, trusts, hurts, and surroundings. Our minds are funny things.

I do this accidentally, but rarely. Our subconscious picked up what the person next to us was saying and we agree with them, but we weren't consciously listening to them. I think it's part of evolution. To fit into society, we all have to conform to a certain degree and these subconscious imitations are part of that.

Sorry for this ad feminen attack but your questions seem rather prolix and you tend to answer your own questions as well. On a deeper level you are looking for a replica of yourself. You won't find this but you will find other unique individuals if you give them a chance.(sic)

I think this person lacks confidence in himself and like the attention you get when you voice your opinion let alone the credit for it, like look how smart she is, she is always right, or people pay attention to your ideas or how they are attentive when you speak.

Generally I don't like those type of people because to me they rob my idea's take them as their own and get credited for it.

Its because they are week.

Cutting through the drama....someone agrees with you, enjoy your moment.
