Nowhere did I suggest to completely discard her parents advice on the matter. Please read my post clearly. All I am saying is that she is mature enough to do that herself. Nobody is denying to obtain the advice or blessings from the parents.
Also I never talked about any scenario being perfect or imperfect. All I am saying is that after 18, humans are usually mature enough for that. I did not reject the possiility of a wrong choice or decision that is why I also said in my first post that nothing wrong in obtaining their advice on the matter.
