Why does Neha mend the old radio instead of buying a new one?

Grandfather's radio had stood on the shelf above his bed for forty years. It was a brown box with a cloth front and a dial that glowed orange. Every evening at seven he turned it on for the news, and every evening the family pretended not to mind the crackle.

Then one evening it went silent. Grandfather turned the knob back and forth, tapped the side, and finally put it down without a word. For a week he sat in the evenings with nothing in his hands.

Neha, who was studying electronics at the polytechnic, offered to look at it. Her father told her not to bother. "Buy him a new one," he said. "They are cheap now. You can get every station in the world on a phone."

But Neha had seen her grandfather's hands in the evenings. She took the radio to the college workshop. Inside, among the dust, she found a burnt-out part the size of her fingernail. It took her three days and four shops to find one like it.

When she brought the radio home, Grandfather turned it on. The orange dial glowed, and the old crackle filled the room, and then the voice of the newsreader came through, a little faint, as it always had been.

Her father said a new radio would have sounded better. Grandfather said nothing. He only turned up the volume, so that the crackle could be heard all over the house.
