===box_example===
I open the door. Inside are four boxes.
I mark them A, B, C, and D.
I have decided to screw around with box D. 
-(decision)What should I do?
//Added conditionals to the choices, if the box has been added, it takes away that option.
+   { not boxA }Add box A
    I open box A, and throw it into box D.
    {open_boxA()}
    
+   {not boxB }Add box B
    {open_boxB()}
    
+   {not boxC }Add box C
    {open_boxC()}
    
    //Likewise, if the box has not yet been added to D, it will not allow the player the option to remove.
+   { boxA }Remove box A
    {remove_boxA()}
+   { boxB }Remove box B
    {remove_boxB()}
    
+   { boxC }Remove box C
    {remove_boxC()}

-There are now {apples} apples and {pineapples} pineapples in Box D.
