There are several ways that participants in a makebelieve can communicate things about the fictional world to other participants. Sometimes these messages are emitted naturally as a result of full participation in the fictional world ─ i.e., something said or done by a player while in character communicates some things that are fictional of that world. For example, a child pretending to be Peter Pan might gasp and draw a plastic knife. This might be sufficient to communicate that fictionally one of Peter's enemies, such as Captain Hook, is approaching. These in-character behaviors can be insufficient, however, to maintain the necessary amount of common ground about what is fictional in the world of the make-believe. At these times participants often come at least partly out of character to give other participants the information they need. For example, it would be important to avoid confusion about who is playing which character: "No, you're Captain Hook, and I'm Peter Pan!"
