My inner 15 year old has come out in therapy more than once for sure. The first time it was when I still saw t in person, and I would sit there on the couch stomping my feet. After we started doing phone sessions, and my inner teenager would get activated, t would say "I can see you stomping your feet." She taught me how to work with my inner teenager, which I've done a lot of, and I've done a lot of that work here on pc actually.
