I always wonder just how well body language really correlates with intention, in general. For example, whenever I'm standing in a pair or group, and somebody walks over, I always consciously reorient myself to help include the new person. But I never seem to notice other people doing the same. I think I use my body language quite consciously, but I usually get the impression that it is mostly unconscious for others. Yet, I can't really know this for sure.
