Section 4 - Heft
A thing has a number called heft. The heft of a thing is usually 2. The heft of an animal is usually 4. The heft of an insect is usually 1. The heft of a bird is usually 2. The heft of a person is usually 4. The heft of a vehicle is usually 5. The heft of a supporter is usually 5.
The verb to weigh (it weighs, they weigh, it is weighing) implies the heft property.
Definition: a thing is heavy if its heft is greater than 3.
Every turn when the player carries a heavy thing (called burden):
try involuntarily-dropping the burden.
Sanity-check waving a heavy thing:
say "Unlikely, unless we suddenly become a good deal stronger." instead.
Involuntarily-dropping is an action applying to one thing.
Carry out involuntarily-dropping something which is not a person:
now the noun is handled.
Carry out involuntarily-dropping:
try silently dropping the noun; [this is better than just moving to the location because it copes with cases where the thing needs to land in a vehicle or supporter.]
if the player carries the noun:
stop the action.
Report involuntarily-dropping:
say "[The noun] [is-are] [if the heft of the noun is greater than 4]far too large[otherwise]too awkward[end if] for us to carry, and fall[s] onto the ground." instead.
Report involuntarily-dropping an animal:
say "[The noun] [is-are] [if the heft of the noun is greater than 4]far too large[otherwise]too awkward[end if] for us to carry, and half-fall[s], half-jump[s] to the ground." instead.
Report involuntarily-dropping the boar:
now the boar is in the location;
say "[You] more or less throw the boar as far away as possible. It seems the wisest course." instead.
Report involuntarily-dropping a person:
say "[The noun] look[s] rather awkward, and clamber[s] out of our ineffective hold onto solid ground." instead.
Report involuntarily-dropping a cat:
say "[The noun] get[s] tired of being carried and leap[s] delicately to the ground." instead.
