Crossroads, a sad vaudeville by Carlos Solorzano who comes from Guatemala. The quote relates to how the woman learn about how the man is looking for a young and beautiful girl like in the picture he has. When the woman realizes the man doesn't recognize her when she lifts her veil -despite having given him hints that she was the woman in the picture- she learns she can never be the woman in the picture so she leaves.
