16 had no curfew, my mom was gone for days at a time... then i got my own place at 17...
moved back to the west coast to my fathers and he would lock me out at 10pm
needless to say i had my own place again REAL quick

my son is 15 and he has to be by 9pm on school nights. on the weekend/in the summer its midnight. yet i'm easily swayed if theres a party or some special event...i'm lucky i can trust my sons judgement.
actually he and his friends usually end up at our house anyway
