That's a great observation, Seeker. It shows that this method of keeping your audience/followers engaged was employed by the ancients long before the WTS got in the 'biz'.
Reminds me of when our kids were small and would get restless on a long auto trip. "We're nearly there, just a few more minutes" I'd say, (even though we still had a hundred miles to go) and they would be satisfied and settle down for awhile until it was time for me to say it again. Of course, if they had been able to read road signs and maps they could have called my bluff, but I was taking advantage of my position of authority so I could manipulate their behavior.
