That was my experience and is my opinion, and I do try not to judge others, but 15 year olds are past the point where they can have jobs and are doing the babysitting. If my friend was treating their teenager this way—assuming their kid wasn't significantly mentally or physically handicapped—I'd ask them why they insist on maintaining such an absurd level of control as to infantilize said teenager on their way into secondary school. I wouldn't insult or suggest overall bad parenting—that's rude and not my place—but if they couldn't grapple with that, I'd probably question my relationship with them in much the same way I'd question my relationship with a parent who refused to let their kid learn about sex or evolution. Based on their level of maturity and actual evident danger in the immediate surrounding area, 8 on the low end, 12 or maaybe 13 on the high end, anything higher and I'd say something's gone wrong, perhaps at the societal level.
