Chapter 2 - Person
Changing to second person is an action out of world. [1]
Understand "second person" and "2nd person" as changing to second person.
Check changing to second person when the story viewpoint is second person singular:
say "The story is already being told in second person. To change back to first person, command FIRST PERSON." instead.
Carry out changing to second person:
now the story viewpoint is second person singular;
say "The story is now told in second person. To change back command FIRST PERSON."

Note
[1]. This turned out to be a good feature to add. Some people really dislike any viewpoint that isn't second person singular.
