Fan Casting Manchild in Sort by Tropes

Although the causes might not be clear, the effects are. The Man-Child, a term invented by William Faulkner, is usually an adult who possesses a very childlike or (stereotypically) childish demeanor. He's emotionally both simple and fragile; he prefers (although does not always need) to have a parent figure to look after him. He usually isn't very worldly and is typically pretty gullible. The Man-Child's interests are usually what most people consider to be immature or childish, sometimes even in comparison to actual children.
