Viennese flexibility and diplomacy

This phrase in my last post may need some explanation. I’m basing the statement on something Jörg Mauthe, an Austrian writer and expert on things Viennese, wrote in his book Wien für Anfänger (Vienna for Beginners). In the second lesson he describes two Viennese coming together. The first one lays out his opinion on a topic. Then the second one gives his–diametrically opposing–opinion to which the first, after a moment’s thought, says, “Ist auch wahr …” (“That’s true too …”)
