She writes different things depending on what we are talking about. Mainly it's stuff in list format but she'll also jot down a short quote of something I said that she thought was significant.

For example, we were talking about romantic relationships and how I am interested in starting one now. She asked me some ways I could meet people and she wrote those down (i.e. join a softball league). She then asked where I was on a scale of 1-10 in terms of wanting to work on finding someone and I said a 6 so she wrote down "6" and circled it. We then talked about some of the beliefs I had that prevented that from being a 10. She wrote down a few short quotes of things I said (i.e. "no one would want to date me").

It's just her way of taking notes. Some days she doesn't write anything and other days, she'll fill the board up.
