There are some folks who understand that things don't always go as planned and some folks who would prefer to trust in providence (or the planning of their company which has taken care of everything). The company may have done a great job in taking care of everything, until something goes wrong or somebody screws up -- it's good to have a Plan B.

If your friend doesn't have or want a Plan B, don't even mention it again. Let him continue to trust in providence; it may serve him well -- it may also serve him up rare. He's not your problem.
