Section - Brooding
Brooding is an action applying to one thing. Understand "brood about/on/over [something]" or "brood [something]" or "think about [something]" as brooding.
Check brooding when noun is not a memory: instead say "Eh. You couldn't really get into a good brood about that when it's this damn cold."
Carry out brooding: say "[description of noun][line break]"; now the noun is retrieved. [We defined earlier that memories can be either buried (not yet brooded about) or retrieved.]
Instead of doing anything other than brooding or trading to a memory, say "As if. All you can really do is BROOD ABOUT it."
Instead of thinking: say "Most of the thinking you do nowadays comes from either smoking or brooding." [Thinking is a standard action which we'll use to hint the player towards better options.]
Instead of brooding when noun suggests a memory: say "It's not [the noun] you want to brood about, it's [a random memory suggested by the noun]."
