People often unconsciously mirror one another during a conversation, smiling together, frowning at the same time, both leaning forwards, and so on. Yesterday I saw a therapist and she was leaning her head on her hand. I started to do the same thing without thinking about it, but the thing I tried to rest my elbow on was a bit too high and then I suddenly realised what I was doing. I often unconsciously mirror my therapists as well, when we're having a good conversation.

Another therapist that I see thinks that mirroring me is important because it's something parents unconsciously do when their children are babies, and it's something I missed out on.
