With fame you can't trust everybody. You can't depend on them being there for you as a person. They will only be there because of what you've got you as a person. They will only be there because of what you've got and what you can bring to their life. It's not a relationship-it's a leech.
This post of President is a Constitutional post. It is the duty of everyone all citizens to see that they respect the post... the institution of President.
