The "another" adjective for rules such as "in the presence of another person".

It is often useful to write action rules which apply only when the player is observed by a third party. "In the presence of a person", however, will react even if only the player is in the room, because the player is, of course, a person as well.

A convenient way around this problem is to define an "other" adjective:

"Finishing School"
The apple is an edible thing carried by the player.
The Hall is a room. Miss Wicket is a woman in the Hall.
The Dormitory is south of the Hall.
Definition: a person is another if it is not the player.
Instead of eating something in the presence of another person:
   say "Your mannerly upbringing prevents you from eating without a fork or knife in front of someone."
Test me with "eat apple / south / eat apple".
Test me with "eat apple / south / eat apple".
Hall
You can see Miss Wicket here.

>(Testing.)

>[1] eat apple
Your mannerly upbringing prevents you from eating without a fork or knife in front of someone.

>[2] south

Dormitory

>[3] eat apple
You eat the apple. Not bad.

If we did not have "another" here, Inform would interpret even the player as a possible schoolmarm, leading to such lines as "yourself stares at you coldly…". Clearly not quite the thing.
