So, for example, I was giving this talk recently in New York City, and I said, "You know when you're on the subway and the other person across the subway car smiles at you, and you just instinctively smile back?" And they looked at me and said, "We don't do that in New York City." (Laughter) And I said, "Everywhere else in the world, that's normal human behavior." And so there's a very instinctive way in which we briefly transmit emotions to each other.
Así, por ejemplo, yo estaba dando esta charla recientemente en Nueva York y dije: "Ya saben, como cuando uno está en el metro y la persona de en frente nos sonríe y uno instintivamente devuelve la sonrisa". Y me miraron y decían: "No hacemos eso en Nueva York". Y yo les dije: "El resto del mundo lo hace es un comportamiento humano normal".
