I haven't trusted therapists' facial expressions since No. 2 blithely admitted to me, "we reflect your emotions back at you."

So when they look sad, it's because the client is sad, or they think the client is sad, or they think the client should be sad. The last two are where their expressions get to be jarring for me - because I may not be sad, or maybe I'm being poker-faced and I don't want to look at someone's sad face.
