"Nari! Nari!"
A boy ran through grass that was tall enough to hide his feet, which cushioned his fall when he tripped. He rolled twice more than necessary, tumbling with the last remnants of his baby fat before springing upright to reorient himself. On his cheek were the stains of his tussle, but the chlorophyll was already oxidizing brown. Giggling, he ripped up a handful of grass, to complement the flower crown that dangled from a bent metal wire gripped in his other fist.
His goal was a girl in the distance, standing at the foot of a tree that supported the sky (at least, from his vantage point; though he was still in the flickering penumbra, even the twigs at the ends of each daughter branch were thicker than his torso, with leaves that he could have used to hide from the rain like the little frog that he was). He continued to run as a brisk summer breeze flexed the tree louder than a thunderstorm, and dodged a brief shower of petals before finally arriving at his destination.
"Nari, look!"
Grey thrust his arm as high as it could go. Though he stood on his tippy toes, the wire that separated the flower crown from his hand dropped it to just below her chin.
"A flower crown?" A young Nari turned from the tree and flinched when the wire caught her chin. She pinched the twisted stems and lift it from the metal hook, holding it up in the umbra of the great tree to examine its pedigree. Shy, pink buds dotted the green, young twigs, hiding their brilliant red petals.
"They're not ready to bloom yet, Grey!"
"Well, how was I supposed to know that?" Grey kicked the grass under her shadow.
"Obviously, because-" Nari sighed and nominated herself queen of the great tree. "It's nice, Grey, but I'm not really into these kinds of things anymore."
"Oh."
"Why not?"
Nari tucked several strands of hair behind her ear, and raised her nose by a fraction. "Because, Grey. They're teaching me important things at the institute now. Natural categorization. The order of biology. The cycles and periods of the weather. These are all very important things, Grey, and I don't have much time to play anymore."
"Oh."
"... Why not?"
"Nevermind!"
"So ..." Grey kicked the grass, "do you still want to splash around with me?"
Though Nari was prim and educated, in an expertly tailored modest dress of pure green, she could not resist. She at least tried to make a show of it, glancing at him several times, snorting and pursing her lips in thought, while Grey had a wide smile on his face and a twinkle in his amber eyes. Finally she removed her gloves and held her hand out in the summer air, and Grey snatched her fingers and pulled them to the tree, tossing aside a handful of dried, brown grass. They pressed their cheeks against the trunk, so wide it curved out of sight and formed their new horizon.
The bark was warm, conducting the sunlight gathered from its span along troughs that could easily fit an arm. Slowly, the rough surface crumbled, and they slid half inside, whereupon Grey began to scoop out as much mulch as he could until he opened a cavity about his size. Water gushed out as he hit the xylem, and soon he was a boy made of mud, tossing and squelching and squirting and throwing it all over Nari. They splashed and tumbled and tussled and rolled the afternoon away, and when the setting sun finally peeked out from the yawning canopy of the great tree, two children of the same height rose from their little swamp and left a trail of brown footprints back to camp, from which furtive, gentle sprouts peeked. The small wound in the tree had already scabbed over, bulging out in a knot that would one day become an altar.
"I guess it's time for you to go learn about categorization, huh?"
"Categorization? You say the weirdest things, Grey."
"I hope they'll let you see me tomorrow. I had to wait so long for today ..."
"I just saw you yesterday!"
"If you say so ..." Grey adjusted the crown on her head. Some of the flowers were withered, but some of the buds had also burst into full bloom. "I like it when you're my height." A leaf tickled her eyebrow, and when Nari reached up her hands brushed a petal and she beamed and spun around, alternating her hands in his left, right, left, and right as they exited the night of the shade into the twilight.
