I sit on the couch and my t sits in her chair, maybe 4-5 feet between us with a small round table in between. I'm not good at guessing distances but it's a comfortable distance. not too close, not grand-canyonish. the only exception is when I'm doing a sandplay thingy then she's usually standing nearby watching what I'm creating. I like the more informal feel of that; makes me think I'd like the going for walks too. Haven't done it, but I think it would be comfortable.
