Ever share a secret with someone from across the room? That person that seems to know what you are thinking without you ever saying a word. How do you signal your secret thoughts? Do you wink? Do you have a smile that only your nearest and dearest recognizes? My friend and I perfected the non verbal communication after many years of faculty meetings. It was so fun to send her a sly smile and know that she was thinking the same thing.
