A kid can fend for himself even if his parents have gone to Paris, leaving him with no food, electricity, heat, money, etc.
No child can ever be killed...even if they're electrocuted on a high-voltage electric fence that could kill a dinosaur (Jurassic Park).
Eight to ten-year-old kids are the best computer hackers on earth and can break into any system.
Girls who can't find a date to the prom in high school films are usually the girls that, in most high schools, would have almost every teenage boy asking them.
