Don't know...

Undeveloped 2 week pluss old post.  will think about it...

explaining look on face vs. emotions to a young child.  Color examples and know shade.  may see correct shade, but respond based upon interpreting another color, vise-versa.  may see diff color and respond correctly to input, but input wrong.  Or both may be wrong (input and reaction)
so process to back outside, and face is similar, body manerisms similar, but NOT exactly what we feel, if even correct in all cases.  Also, may be pointed in you direction, but in refrence to something else you may or may not know about.  you take it prsonally, when it wasn't about you at all!  (shit, and Im not saying im an exception, cause I ANIN'T)
