Educate me on this please

Is there a definition for a person that hears what you say about everything and decides to adopt it to the point that you have to inconveniently change what you've been use to doing for years..

The reason why I am confused is because some things were said by this person that clearly shows they have some issues with me. So why are they changing from their VERY UNIQUE style and completely (not using completely lightly) attempting to transform to basically my lifestyle???, what I eat, what I don't eat, how I joke around the office, who I talk to, how I DO THINGS -everything.

Example:

I made a comment about where I go to talk in private, and now when I go there, they are always there- so does this person hear what I say, take it from me and make it their own?

And I may have said something in a girl talk group like " these two colors are my favorite colors - well now all they wear are those colors. I had a habit of wearing those colors days in a row but now they do that.

This person always says things like "well they don't say anything when you do it, why is it a problem when I do it. ( I wanted to ask if she attempting to do it because she saw me do it)!

I named a store I get gifts, clothes, decorations from before I go to the mall and they got a job there. It was my favorite store but I am hesitant to shop there now because I know what the outcome will be.

I knew some issues were there (like maybe a little lost) and I just overlooked it until I heard the hurtful things she said. I was a little annoyed but dealt with it but since I know how she feels about me it is beyond annoyance. I know it is not against the law to do everything someone else does but it is so uncomfortable.

Another thing, this person came to me for advice and later told me that although what I told them was the truth, they were offended by what I said and they replied "I'm working on me"- - (oookkkkaaayyy so, since you got offended by my truthfulness, I have to look at me and you came to me for advice?????

Sounds like a person that is not sure of her self, therefore, she is watching and seeking from others - but imo she will never truly be satisfied (or happy inside) until she becomes the person she was meant to be.

(((Rhapsody))) good post.
I agree As being ourselves is who we were meant to be. I know i pick up on good things here and there and thats how i grow and learn.
But I still gotta be me or im not happy

Yeah, want-to-b-fair, I call them copycats!
While people so often say that it's a form of flattery, the truth is that it's darn annoying! Especially when they're doing it on so many facets of your life!
My mother (of all people...) does this, and it has ruined several things for me, in that I can no longer think on the thing without the association. Not sure if it is on purpose, to ruin something (not out of the question) or if she geniunely thinks it is some way to bond. As a result, I hold back things I don't want ruined. Conversation is, well, limited. (So, it really doesn't work for bonding, does it?!) I don't know if that is the best approach, but it does help me set a boundary. (Well, that, and 3000 miles helps too.)
Best of luck and here's hoping she takes up her own thoughts and interests soon!
