I notice what she is wearing and her posture, and facial expressions - I think I am a good reader of body language. I also notice when things change in her room. She has all these small sculptures and figurines on her bookshelf (in front of a whole bunch of interesting looking books) and sometimes she moves them around. I noticed almost immediately when she got a new one - a little tree with gems hanging from the branches that moved in next to a knight's chess piece and a small silver dog, LOL.

I also notice when she dusts the shelf and when she takes a book out of one spot I always notice that too (sometimes I notice which book is missing too). I have a very good memory so I do this in most cases, I guess I am just particularly tuned to that bookshelf - I look at it a lot during sessions.

I'm sure she is observing me observing too
