I'm totally serious. You'll learn techniques if you start by acknowledging, if you start by saying, "You know, we don't agree on a lot, but one thing I really respect about you, Uncle Bob," or "... about you conservatives, is..." And you can find something.
Aprenderán técnicas, si comienzan con reconocimiento, si comienzan diciendo: "Sabes, no estamos de acuerdo en un tema, pero una cosa que realmente respeto de ti, tío Bob..." o "... de los conservadores, es..." Y se puede encontrar algo.
