His fingers drummed a restless rhythm on the tabletop, a counterpoint to the quiet intensity emanating from the corner of the living room. Leo, his son, was hunched over the workbench, lost in the world of model trains. The tiny locomotives gleamed under the soft glow of the lamp, their intricate details reflecting a passion he no longer recognized in himself.

He used to spend hours meticulously building tracks and crafting miniature landscapes. The click and clack of the trains used to be a source of joy. Now, the sounds were a reminder of a past he couldn't revisit. He swallowed, a lump forming in his throat. He felt an ache of separation from something precious, a sense of having misplaced a vital piece of himself.
