Why would it be obsolete? Very good description of how to accustom the uninitiated to firearms (or really, any new/scary thing)? If at all possible, starting away from the firing line of the rifle range is best, and sitting in one's comfort zone of their living room is a great place to start.
Me either? Are you worried your (after much trying, presumably now to become ex-)wife will scream blue bloody murder and get your stuff taken? Always have a buddy you can store your guns at?
