Inference about John's Interest in Astronomy

Read the following passage:

John had always been fascinated by the stars. Every night, he would lie on the grass in his backyard, gazing up at the twinkling lights in the sky. This passion for astronomy grew even stronger when he received a telescope for his birthday. He spent hours observing planets and distant galaxies, often losing track of time. His friends would tease him for spending so much time outside at night, but John didn’t mind. He found joy in uncovering the mysteries of the universe.
