Yes. And interestingly, on that note, a few weeks back I told her I had gotten into a fight with my mom because I told her I didn't want her to open my mail anymore (I was living with my boyfriend for 4 years but still had my mom's address listed as my permanent address so some things were still coming to her house, mostly bills that I didn't need because I see them online- and I recently moved back with my mom). My mom insisted on opening the mail in case something important came through - she would never open anything personal though. The therapist was SO fixated on how awful it was that my mom opened my mail, even though that wasn't the point I was trying to make about why I was angry with her, just a side story.

It occurred to me that maybe she was thinking (hoping?) that my mom would intercept the letter and read what she wrote about her.
