Oh goodie, bad analogies.  Can I play too?

Getting to office 215 is not analogous to writing a program.  It is
analogous to using the program.  Writing the program is like building
the office tower.  You need to know about the tools and materials that
you are working with.  You don't use "common sense" to decide what
materials to use.  You study the literature and the specs.
