I would be uncomfortable with a therapist who explicitly referred to boundaries. My therapist and I don't have explicit discussions about boundaries. He seems relatively loose with them, and neither one of us really seem to do anything that would bring us near any boundaries and prompt a discussion about them. Allowing for phone calls is part of how he works, and he has a really good system for coaching if the need arises between sessions. I feel like he's really confident about how he handles these things and he is so clear about how they work that boundary issues just don't come up.

Sometimes it sounds to me that therapists seem to talk about boundaries when they don't seem very secure or confident in themselves, like they need to assert something to counteract something that is showing up for them. But I don't have any personal experience with this so it could be that I am misunderstanding other people's experiences...
