Curiosity is the spark that starts a flirtation—in a bar, at a party, across the lecture hall in Economics 101. And curiosity ultimately nourishes that romance, and all our best human relationships—marriages, friendships, the bond between parents and children. The curiosity to ask a simple question—“How was your day?” or “How are you feeling?—to listen to the answer, and to ask the next question.
