Karen, You're right, back-up plans can mean and manefest different ways. One variation is more aligned with what you describe, using a different method or activity to make a point or teach a principle. Back up plans can also mean having a set of preplanned activities that can be implemented on short notice in the event whatever was planned cannot occur for whatever reason. Really, in any situation, we should be prepared to offer an alternative way (or ways) to deliver our message. Barry Westling
