I'm lucky - my T is the opposite of poker face. She's so natural but not obtrusive. We laugh a lot in session and she mirrors me very well. When I'm in distress, you can see on her face that she 'feels' it in some way also. Again, not obtrusive but very empathic. Her 'poker face', if you could call it that is when she's concentrating very hard on my attempts to communicate with her but when I'm done talking she responds always very appropriately with just the right amount of very human connection.
