Season 20 should end with everything getting nostalgia ' d , and Season 21 should open with one of these . The boys go to class , to be taught by Mr . Garrison and Mr . Hat . That would honestly be a trip . <| sep |> But I ' m not about to be President of the United States of America . <| sep |> I ' ve had a few . Not in the last few years though . <| sep |> At a time in your life when you are becoming a separate adult , testing the rules , and trying new things , you need to stop worrying about your parents . Making big decisions on your own generates a lot of anxiety in many of us , whether the decisions are good or bad . We often focus on something that we think will make us feel better and stop the worry and anxiety . Your parents made you feel good when you were little . Sadly , that phase of your life is over . Let it go . You no longer need their approval and encouragement . Let that go too . Nothing good could come of telling them . It won ' t make anyone happier if they know more about your growth and development . Instead of putting your hopes and energy into yesterday ' s relationships , put it into building your new life . Your job now is to look forward , not back .
