Due to the nature of large polyatomic molecules it is inevitable that there is some overlap, simply because of the energy gaps between the antibonding/bonding molecular orbitals being relatively large compared to the gaps between the valence atomic orbitals.

If my metaphor is a perfect one. Which, as I repeatedly note, it isn't.

I'm confusing nothing. I know methane's molecular formula; in fact, I use the molecule as a prime example of tetrahedral/tetrahedral bonding when I help the neighborhood kids with their chemistry. I was talking about the forces between molecules (Van der Waals forces, etc). That's why I used terms like "band gap" and "conduction bands", two phrases that apparently have no meaning for you. Perhaps you need to consult with that materials sci guy down the hall after all. And of course, you missed my main point, which is self-evident on this site. But be careful, your colleague can't do anything about your tendency to see showers of bats* everytime you read my prose.
*Hint: follow the bats to the section under Semiconducting and Insulating solids: Band formation in extended covalent solids.
