I thought this would brighten a gray, wet November day.
With a little research , I learned the origin of the head bobble… dating back 400 years when the kings in Indian did not like to be confronted with a “no” when they gave an order. This was true up to and through the Colonial period with the British. Indian people adapted by not saying no to a request. Well, sort of ! For people from other cultures it can be rather confusing as you can see from this presentation!
