Time to start charging rent, grocery bill, phone bill, water bill, cable bill, electric bill, car insurance, health insurance, internet service,car payment, and her own fuel, buy her own clothes, the washer and drier now takes quarters(lol), she needs to wash her own dishes and cook her own meals as well....and IF she can pay/do all those, then yes, she IS old enough and adult enough to do what she wants. Pretty simple.
