** Ditto for just about everyone in ''{{The Melancholy of Haruhi Suzumiya}}'', also released by same company Kyoto Animation. That is, except for Haruhi herself and Kyon's ten-year-old sister.
*** Ironically, [[PuniPlush quite the opposite]] was true with another K.A. work, ''{{Lucky Star}}'', where the "teenage" girls look, talk, and sound like preteens. The cutesy music and pastel-colored artwork only makes this series feel more like elementary school than high school.

* NowAndThenHereAndThere. It's justified though. [[ChildSoldiers And we wish it wasn't.]]

* Justified in ''KimPossible'', as Kim's twin brothers are [[ChildProdigy kid geniuses]] from a genius family.

Please note that there is an inverse function to this trope - most writers are adults, but are so aware they're writing for children that certain activities will be excised from underage characters even if it's realistic for that age. So your sixteen-year-old won't be dying to get laid; they're searching for true love, and [[RelationshipWritingFumble all relationship interactions will be completely romantic rather than sexual]]. And they'll ''never'' smoke, drink, or get high unless it's a VerySpecialEpisode or the character's an antagonist. Also note that children acting in [[TroublingUnchildhoodBehavior ways that they shouldn't be able to, i.e. like adults,]] is also a common [[CreepyChild go-to Horror Trope]].

* TamoraPierce. Most of her protagonists start out at around ten and grow into their late teens or adulthood, and all the way through they think the same, act the same and talk the same. The CircleOfMagic books, for example, feature a FourTemperamentEnsemble who all become accredited mages at the ImprobableAge of fourteen and thereafter mix (aparently exclusively) in adult circles, and any character who ever suggests they might not be as mature, capable or knowledgeable as older people is either a JerkAss to be publicly humiliated, a villain to be defeated, or both.

Part of the problem with writers writing like a child is that ''their writing sounds childish'' - which is why this is an omnipresent trope. Consider how many people hate the InheritanceCycle - written by a teenager. Also, do not underestimate children; there are pre-adolescents who vaguely understand sexual matters from an intellectual viewpoint, read encyclopedias and other adult literature, and in the past were apprentices in various trades - so they cannot afford to act or speak childishly.

* As ''TheNostalgiaCritic'' pointed out, the "kids" in ''Film/TheWizard'' talk more like 1980's businessmen. That's not even getting into the pedophilia implications of one scene.

* ''[[OjamajoDoremi Doremi]]'' of the anime with the same name falls in love more often in one season than other people in their whole life. And she is 8 at the start of the first season.

* ''{{Doremi}}'' of the anime with the same name falls in love more often in one season than other people in their whole life. And she is 8 at the start of the first season.

* Stewie from FamilyGuy. Remember, he's ONE year old. Still.
--> Brian: I mean, you are getting a little old to have a teddy bear.
--> Stewie: Brian, I'm one!
--> Brian: Still?
--> Stewie: What?

* Averted in the works of RobertCormier. His teens swear, masturbate, drink, fight, and just generally flaunt the artificial limits imposed in the majority of American literature.

** In AllGrownUp, the kids are 11-13 years old but they all act like they're about 15.

* As ''ThatGuyWithTheGlasses'' pointed out, the "kids" in ''Film/TheWizard'' talk more like 1980's businessmen. That's not even getting into the pedophilia implications of one scene.

** Once she [[TalkingTheMonsterToDeath starts expounding at the villain]], any pretense she's supposed to be a young girl goes flying out the window. Terry Pratchett can't write kids.

* Beautifully averted in Steven King's ''{{It}}''. One of the reasons the book is so compelling is that King really gets the way children think and reason.

* Stewie from FamilyGuy. Remember, he's ONE.... Still.

* ''{{Runaways}}'' focuses on a group of preteens and teenagers living together without any kind of adult supervision. For every example of the characters acting their age--insisting that adults can't be trusted, not knowing about current events because they've been watching ''{{Friends}}'' reruns instead of the news--there's a dozen examples of them handling situations most adults would find overwhelming. And while most of them go through crushes like any normal teenager, two of their relationships become quite serious: Gert and Chase act more like husband and wife than boyfriend and girlfriend, and Xavin and Karolina are actually engaged. (Granted, it started out as an arranged marriage to end the war between their worlds, but they stayed together long after that arrangement fell through.)

** This trope is actually averted if anything, since the most of character's idea of romance is either a case of short, innocent crushes that kids normally have, or trying to emulate the romance they think adults have, which some do.
