rite age to make children independent

[wellness]

children are growing too fast now a days..

but still the rite age to make them independent is 15..
independent i mean.. we can stop worrying about them by then.. this i have observed personnaly..

[ENGLISH]

15 is too young for a Child to get independent dude parents will always care about their children even their age crosses 50.No one can't stop it.Making Independent doesn't make sense.Rather parents can behave too much friendly towards their children so that the gap for need of in dependency can be filled.
