Do americans curtsey or bow to the queen?

No, we do not even bow to our own leader, it may seem disrespectful, but in the American culture a nod of the head will do. We broke off from England with a war, and will still respect that as part of our history, so to some bowing to an english queen may even feel wrong even if that war was over 200 tears ago. We are nit obligated to bow and the royal family respects it, as long as we keep our manners
