At what age are kids grown up.
There are people who are forty and still not "grown up"..
depends on how mature they are...
Never...nobody ever truly grows up...but you see the biggest change in maturity in your mid 20's...anyone under 18 is just pretending to be a grown up!!
when they can be put in federal prison for committing so 17 or 18 so says the state may vary from state to state though
