> Classifying accounts as child accounts

It's ok to drive Dad's truck unless he catches you and tells you no.

Unfair presentation. What they suggested was more akin to, "Assume someone with keys is an adult, and let them start the truck."

Dad should either know his children would never drive the truck without permission, or keep his keys as safe as his wallet (and if he can't trust his kids with keys, you bet his wallet needs protection).
