Nesting and Looping – To fit one thing (outcome, story, etc.) within another. Also referred to as Looping.
For example, begin to tell a story and leave the listener(s) with a cliff-hanging moment and segue onto another story or subject.
This generally keeps the audience’s interest while you provide other information you wish to convey. Once you have finished implanting the other information, you then return to close the loop by finishing the original story.
This is a common practice used in television and many books.
