There’s something intensely unhealthy going on when parents discourage age-appropriate independence. A 13 year old should probably be allowed to go see a film with their friends most of the time. A 16 year old should probably be allowed to drive/ride a bus/bike to a friend’s house most of the time. An 18 year old should probably be allowed to travel overnight with their friends most of the time. A 20+ year old should be allowed to come and go as they please, with some common-sense “Let’s talk this ‘move to Finland’ plan of your over before you follow through on it” exceptions.
Parents should want their children to enjoy going out and doing things on their own and with their friends. They should be delighted that their child wants to have a life of their own. A rich, fulfilling life outside the home and distinct from parents and family is important, and parents should want their child to have that.
