The click, whirr, and whiz of the model trains no longer sparked joy. The layout, a miniature world of meticulous detail, sat frozen, untouched, and gathering dust. The station lights no longer seemed vibrant. It was the lack of company that stung the most.

His son, David, however, was in the basement with the trains. He had added new buildings and landscapes, and now the tracks were fully operational. “Dad, come see the new tunnel!” David called, his voice thick with excitement. He looked up, his eyes meeting his father’s. A smile spread across David’s face as he explained the changes. The father's heart stirred. The echo of the silence had receded.
