My T has never asked my permission for a student to sit in on a session. If she did, I’d say yes. Absolutely. In a heartbeat. I would feel comfortable with that at this point in my life and given how far I’ve come along in my progress. It reminds me of my own years as a student doing graduate and post-graduate work. I was always so grateful for all the people who participated in my surveys, interviews, research, etc. I guess agreeing to let a student sit in on a session(s) is my way of paying it forward.
