And I think you are being a bit over-sensitive on his behalf. Nothing I said insults the President or is unflattering. It simply is true. Heck, he even wrote a book about the art of negotiation, which is something only a person who believes strongly in his powers of persuasion would do.
Strong self-confidence, persuasiveness, and an outgoing nature are great qualities for anyone to have. They are a big part of why such personalities often succeed in life. However, these same qualities can be a detriment in some situations. Speaking with Mueller is fraught with danger for President Trump. It's a potential disaster waiting to happen. This is one time the President should trust his lawyers instead of his own naturally open inclination.
The insult is assuming he’s stupid enough to think he can really talk to Mueller without getting himself into trouble. You make him sound like a boastful little boy. I prefer to trust his instincts and his innate understanding of human nature.
