A light skipped into Henry's chest as he sat down. His sister's daughter, Sophie, was hunched over a drawing, tongue peeking out. He leaned in, and his breath hitched. The picture featured a sunny field, a small cottage, and a familiar, furry form. "Barnaby." He felt a lightness, as if he could float.

He grabbed a crayon and made a swing set for Barnaby. Sophie clapped her hands and then looked at her uncle and smiled.

"Now, we need a slide!" she shouted, and Henry knew that he had to draw one.
