Chapter - The Ghost
The ghost is a person.
Ghost spontaneously acting is a truth state that varies.
Persuasion rule: if ghost spontaneously acting is true, persuasion succeeds.
First unsuccessful attempt by the ghost doing something when the ghost is not visible: do nothing.
Check the ghost examining when the ghost cannot see the noun: rule fails.
Unsuccessful attempt by the ghost doing something:
say "The ghost goes through the motions of [subjectless form of the current action].".
Rule for implicitly taking something when the ghost is the person asked and the ghost is not visible: do nothing.
To say subjectless form of (X - a stored action):
let T be a stored action;
now T is X;
now the actor part of T is yourself;
now the request part of T is false;
say T.
After the ghost examining something: say "The leaves swirl toward [the noun] as if the form within them is peering closely at it."
After the ghost taking something: say "The leaves swirl around [the noun] and it rises into the air among them, where the ghostly figure's hands might be."
Carry out the ghost opening a door when the player can see the noun: say "The ghost opens [the noun]."
