Yes, I experience this. I do it with my journal. She respects my line of what I will read out loud, what I will summarize out loud, what I will ask her to read silently to herself (never had her read it out loud to me), and what I give her to read between sessions. Many times it is a push to read it out loud. My T does not have this information ahead of time, unlike in your situation; so she doesn't have time to prepare for a response or what have you. She is able to see first hand how difficult it is to say the items out loud. Today there were 2 important things in my journal and the session/day had already been tough so I said that I wasn't going to read them and that I was uncomfortable with her having them as they were in her copies of the journal. For a change, she didn't ask if I wanted to hold on to the journal pages. In the past, she was always clear that I never had to give her the journal pages and using the journal this way was my idea. We did talk about why I didn't want to read them, what I was feeling around them.

I hope that helps.
