A/N: Features Peter and Tony with the prompt: "Person A strings popcorn on the tree while Person B eats all of the popcorn."
Anyone walking into the kitchens of the Tower should have been prepared for anything by now, and, yet, Tony was still shocked when he entered the room to see Peter apparently trying to re-create a blizzard with nothing but popcorn.
"Kid, what are you doing?" he asked, staring at the mounds of white that were sitting on the counter, spilling out of the largest mixing bowls in the kitchen.
Peter looked up from where he was sitting at the island in the middle of the kitchen, holding a needle and thread. "Making popcorn strings," he said. "It's a tradition."
The Stark family hiring an interior decorator every Christmas since he was a kid hadn't really lent itself to things like 'traditions' and Peter must have realized it because after a minute he clarified his statement. "They go on the tree."
"The tree," Tony repeated, wondering if he'd heard wrong. Why would anyone put popcorn on a Christmas tree?
"Yeah," Peter replied, picking up a kernel and carefully threading the needle through it without ruining anything.
Tony shrugged, giving up on figuring out what exactly was going on and walking past Peter to try and find the coffee maker. "Okay, kid. Have fun."
The coffee maker turned out to be not that hard to find after all, and Tony had no trouble finding a mug since Steve and Bruce were both in the habit of consistently washing the dishes. Soon, he was making his way back out of the kitchen, picking his way around the piles of snack food.
"Do you want to help, Mr. Stark?"
The question caught Tony off guard. "What?" he asked, turning around to look at Peter.
The kid repeated his question, gesturing to the stool next to him. "There's lots to do – do you want to help?"
Childhood in the Stark home might not have leant itself to traditions, but maybe it was time to start learning some new ones, Tony figured. Sitting down beside the kid, he grabbed a handful of popcorn and started handing it to Peter one piece at a time.
And if more of it ended up being eaten than actually going on the tree, it probably didn't matter that much anyway.
