Wigglers & Nodders

They wiggle, we nod. It is common and stereotypically Indian to uses a side to side wiggle of the head to express many things. To do it you lead with the chin and roll it to the side about 15 degrees then rapidly snap it to the the other direction. Becoming aware of their wiggling made me aware of my own up and down nodding; both gestures used to express our feelings and add meanings to our words. I've searched the web and You Tube for good examples but none found. They use the wiggle to express things like, 'yes', 'of course or duh', 'I dunno', 'well...', 'hiya' and depending on context and facial expressions, 'no' and 'yes, but'.
