My T forgot her keys once and we went to a local cafe to have our session! I think it depends on the relationship and needs of the client and how the therapist works, etc. I know when I was a 6 or 7 I use to climb up on top of my dresser in my room to get a "different" view. Perhaps walking outside where you are not so "confined" will help you feel more comfortable and help you talk a bit more. I think it is a nice idea, shows the T's willingness to try different things to help you rather than just stick to a script.
