Children brag about exclusive knowledge even when the secret is fabricated.

Evidence

Among children, pride and bragging are often based on a child’s being able to say to the other: “I know something that you don’t know” and to such a degree, that this sentence is uttered as a formal means of boasting and of subordinating the others, even where it is made up and actually refers to no secret. — Georg Simmel, The Sociology of Georg Simmel, 8062
