I am also bemused that my T will sometimes share something pretty person, but then refuse to say why he chose a huge print for the wall of the waiting room. I've found out things just from life happening- such as that my T dislikes/is allergic to dogs ( I love them), bc the office down the hall brought one and let it wander the floor. His face told all, so then he sheepishly confessed . He nodded to my dog stories, and gave no sign before that. That is when I realized therapy is a strange interaction.
