John felt like he was floating as he carried his boxes up the stairs. The house was exactly as he remembered, and it filled him with a curious kind of elation. He reached his room, and gave a joyful whoop. He decided immediately to rearrange his childhood posters, giving each an appropriate and comical assessment.

He raced downstairs, rummaged through the cookie jar, and then started a game of tag with the family dog. He laughed as the dog's tongue lolled out, and it's tail furiously wagged. He felt unburdened.
