Aunt Clara bounced into the living room, a grin splitting her face. Little Lily, her niece, was meticulously coloring a picture. “Whatcha got there, sweet pea?” she chirped, dropping to her knees. Lily mumbled something about a unicorn. Clara peered closer. Nestled beside the rainbow-maned creature was a lanky, green figure with oversized eyes. Her breath hitched. A figure she hadn't thought about in twenty years, the exact shape of "Greebles," her childhood confidant. A giggle bubbled up from deep inside.

She snatched a crayon, a bright magenta, and added a ridiculously large hat to the green figure. Lily giggled too, and then gave her aunt a suspicious look.

“Can I draw too, Aunt Clara?” she asked, a mischievous glint in her eyes.
