Day 31: Lie to me

So, one of my new favorite shows comes on Monday nights and is called LIE TO ME!  It is such a great concept.  This guy's job is to read people and solve crimes.  He is very witty and a little rough (kinda like House) but it is amazing how much we say or don't say by our expressions and our actions.  Josh loved it so much he started to try and "read me"...not fun...but it got me to thinking...what am I saying when I say nothing at all?
