When we started talking about holding a family talent show to liven up reunions, my sister-in-law, baby brother’s wife, lamented that she doesn’t have a talent. We corrected her. Everyone has a talent. Someone else might have to identify it for her, but everybody has one.
The identification of a person’s hidden talent is usually a discovery made by some objective observer. Up until the moment of revelation, no one may know such skills existed in ordinary humans.
