Most of us have been snubbed in our lives.  Trying to land the big client only for it to be made obvious that they consider you too small-time.  A coach not giving you the opportunity in a team sport because of their preconceived notion about you.  A high school clique from which you are shunned.   A sorority you were denied entry into.  A venue you can't play because you're not on the current list of hot local acts.  And so on.

For Donald Trump it was not being allowed into the inner circle of Manhattan society, no matter how much money he had.

Most people get over the hurt feelings.  Even if you land the client or the gig or are befriended by a clique member there's a little voice in most of our heads telling us to stay cool.  But Mr. Trump seems intent on rubbing people's noses in it, because his emotional development was arrested at the age of 15.  He is the embodiment of what my friend Guy Forsyth penned: "I wonder how the world sees us: rich without equal, powerful beyond compare, a spoiled teenager waving a gun in their faces."  So he courts Mitt Romney simply to pull his hand away and say "psych!"  He nominates cabinet members that are unconventional, not to shake things up but to thumb his nose at the people who never let him in the club.  His "thank you" tour is full of nanny nanny boo boo commentary about the media, Hillary, even those to whom he's made part of his administration (Reince Priebus, for instance) because they dared to denounce him.

That same lack of discipline or ability to know when to let something go has caused him to pick a fight with the CIA over their assessment of Russian hacking.  And now he asked for records of civil servants in the Departments of Energy and Interior that worked on any climate change projects, presumably as a threat to fire them.  Mind you, these are career employees who likely did what they were told.

This pattern is not going to be modified nor applied with any reasonable filter.  The man is 70 years old; he's not going to change.  He simply has development that's been arrested for 55 years.

Speaking of cabinet picks: Rick Perry to head a Department that he couldn't remember he wanted to shut down.  That should work out well.
