He found it late one evening, scrolling through listings while procrastinating on a work project. The familiar address blazed across his screen: 3 Oak Street. A smile spread across his face, so wide it hurt. He leaned back in his chair, feeling loose and limber.

A wave of impulse swept through him; he immediately called his old friend, David. "Remember that treehouse?" he asked, voice buzzing with excitement. David's sleepy "Yeah, what's up?" turned into a shared wave of nostalgia.

The next day, driving the familiar route, he felt a powerful urge to open the windows and breathe in the crisp autumn air. He parked, hopped out of his car, and strode towards the house with an unusual bounce in his step. The house, freshly renovated, felt both familiar and new, a perfect blend of past and present.
