He was his _friend_, and considered it his duty to be honest and open--and if necessary, disagreeable.

The Archduke understood, appreciated, and valued this attitude.

I do not think there are many monarchs or heirs to the throne who would have suffered, as the Archduke did, Schwarzenberg's sayings and doings.
Franz Ferdinand was on very bad terms with Aehrenthal, who easily became abrupt and repellent.

Still, there was another reason why two such hard millstones could not grind together.

I do not believe that the many reproaches launched against Aehrenthal by the Archduke were consequent on political differences; it was more Aehrenthal's manner that invariably irritated the Archduke.
