    "The Magic Word is not XYZZY"
    
    Include Player-Character Requires Persuasion by Ron Newcomb.
    
    A Quiet Spot is room. Bob is a man in the spot.

    Persuasion rule for doing something when said please is true: persuasion succeeds.

    Persuasion rule for asking Bob to try sleeping or waiting: say "'I'm already trying to, thanks.'" instead.

    Test me with "sleep / bob, sleep / wait / please wait / bob, wait / jump / bob, jump / please jump / inventory / inventory please / bob, take inventory ".

    Said please is a truth state that varies.

    After reading a command:
        now said please is false;
        if the player's command includes "please" begin;
            now said please is true;
            cut the matched text;
        end if.
