What you hear later is, again (just like the beginning) one of the most
common, ordinary devices used in tonal music:  running up and down the
tonic chord (or any triad chord).  You can find this in almost every tonal
work.

You are entitled to your myths, of course.  You're not the only one to do
so.  As I wrote previously, it's much easier this way.
