Hofstadter is the son of Nobel Prize-winning physicist Robert Hofstadter. This should be part of a Marines-type training course for readers. It would even be misleading to attribute it any meaning at all, since it is not well-formed, and our meaningful interpretation is entirely derived from looking at well-formed strings. In much the same way, we build language based on isomorphisms. But she doesn't seem heart-broken in the least.
