At play, at work, at home

In Save the Cat, there’s the concept of “at play, at work, at home.” It seems this is just an awkward way of trying to tie the RS, IC, and MC into the OS. If you are familiar with this concept, how would you line up these three? I’m guessing:

  • play: OS/MC
  • work: OS/IC
  • home: MC/RS

The slashes merely implying there is a crossover. The words play, work, and home suggest setting more than throughline, but it seems like it’s tapping into the MIND and the realms (domains) they represent.
