Question

An excerpt from a contemporary story set in Tonalá, Mexico, describes a glassblower named Alejandro:

For forty years, Alejandro had stood before the roaring furnace, holding a long hollow pipe. He watched the molten glass glow like a miniature sun trapped in his workshop. With a steady breath, he blew into the metal tube, shaping a delicate amber vase. The glass expanded, responding to his lungs as if it were a physical extension of his own spirit. His grandson, Leo, watched from the shadows of the workshop, captivated by the orange light dancing on the walls. Alejandro did not speak; his movements were a silent choreography of heat and gravity. He knew that the craft was not merely about creating functional vessels, but about capturing a single moment of warmth and breath, locking it in a fragile, frozen state for others to hold long after his own hands had grown cold. He guided Leo's hands to the pipe, sharing the warmth of the glass.
