BINARIES THAT NEED A THIRD THING

So there's this little game I play with myself. I try to think of binaries—two things that are opposites. Or a balanced set of two. A yin and a yang. Or a very famous pair of things for which no third thing comes even close to the first two. And then I try to think of the third thing. What is right in the middle? Or something equally awesome?
  1. 1.
    Maybe this still makes no sense to anyone but me. Here are some examples of binaries, to my mind. And after each binary is a third thing I came up with IN ALL CAPS. It is important that the binary is a perfect set of two and isn't missing anything as two things. But then you add the third thing and it is also a perfect ternary or trio, too!

    Mac. Windows. LINUX.
  3. 3.
    John. Paul. GEORGE.
  4. 4.
    Black. White. GRAY.
  5. 5.
    Fork. Spoon. SPORK.
  6. 6.
    Male. Female. HERMAPHRODITE.
  7. 7.
    Hot. Cold. WARM.
  8. 8.
    Left. Right. CENTER.
  9. 9.
    Axis. Allies. NEUTRAL.
  10. 10.
    Happy. Sad. APATHETIC.
  11. 11.
    Democrat. Republican. INDEPENDENT.
  12. 12.
    Coach. First Class. BUSINESS CLASS.
  13. 13.
    We are NOT looking for perfect sets of three. No Earth, wind and fire. No red, white and blue. No hop, skip and jump.

    Anyway, if you've gotten this far, here are some binaries that I have not found the third thing for yet. Help me? Or come up with other binaries and their third things:
