I have no idea if this is what you had in mind, but here you go!
Kris doesn't cry as Mikey pushes him over and takes his ice cream, but then he never cries. He just stands up awkwardly and digs one toe into the dirt and looks around, wide-eyed and disappointed. His parents are having a coke with Mr. and Mrs. Gokey so they didn't see anything, and if any of the other kids did, they aren't admitting it.
He sort of twists his arms together and laces his fingers and bites on his lip, and finally decides that maybe Mikey's parents never get him ice cream, and Kris's parents get it for him all the time, so it's okay if Mikey has it. Maybe he just needs it more.
But he doesn't know what to do with himself now because Danny is playing with Matty in the sandbox and Meggy and Lilly are playing with each other's hair by the monkeybars, and unless he wants to play with his little brother, Kris doesn't really know anybody else here. So he digs his toe into the dirt a little more, then turns around in a circle and starts wandering off towards the swings.
There's just one other boy there, blond and freckled and dragging his running shoes against the ground as he slowly swings. He still has his ice cream.
"Hi," says Kris, stopping in front of him and sort of looking at him and sort of looking at the free swing as he digs his toe into the dirt again. "I'm Kris?"
He says it like a question, and is so relieved when it's actually kind of answered. "Hi, I'm Adam," he says, stopping the swing as ice cream drips down the cone and onto his knuckles. "I'm new."
"I'm not," says Kris awkwardly. "But my friends are all, you know...kinda busy." He doesn't think they're doing it on purpose or anything, and he's sure they'll all play together again tomorrow, but for now it leaves him standing alone.
Only he's not alone right now, not anymore. At least, he hopes he's not.
"Sometimes when I'm alone, I play on the swings so the bigger kids don't pick on me," says Adam, and that's when Kris knows that Adam saw what happened, even if he's nice enough not to say so. Then he holds his melty ice cream cone into the space between them. "Do you want to share my ice cream? There's too much just for me."
"Yes, thank you," says Kris politely, but as he sits down on the swing next to him he can't help breaking into a shy grin. A moment later, as Kris licks the ice cream, Adam grins back.
This is perfection, exactly what I was hoping for! Kris is the most adorable little boy ever, of course he has always been that nice:) And knowing how much Adam loves ice cream, it means a lot that he would share it. Thanks so much for filling this prompt.
