I considered projection, but that's not necessarily it at all: you're talking about her using a similar style, you don't mention any emotional content. I think the key is talking it through with your therapist more than worrying about what term it might be though.

Here are a couple definitions for you though: http://www.britannica.com/EBchecked/...472/projection
http://www.britannica.com/EBchecked/...2/Transference

If you did mean that she was acting negatively, such as rude or hostile, when you said "what goes around comes around" that might be tied to projection but it's hard to say with no info. Your therapist should be able to help you understand her intentions if you ask her.

I often ask mine: "Why did you say X" or "What did you mean by that?" Or, "Are you trying to be __________" when I'm not sure what feeling she's trying to convey. She doesn't seem to mind. I think it's better to ask than guess so we don't have misunderstandings fester.
