Chocolate Syrup
“You said rock-stacking wasn’t a real hobby, so I used your laptop to look up actual things that Muggles do with rocks. And get this! Some Muggles do actually stack rocks, but they do it at national parks and that’s frowned upon. So I won’t do that anymore. But rock painting is a generally approved of activity, and Muggles leave their painted rocks around for other people to find so they can ‘have a little magic in their day.’ So I transfigured one of my rings into a rock and painted that, since you said I have too many rings anyway, and then when a Muggle picks it up, it’ll turn back into a ring, and then they’ll be delighted with the magic in their day! How about that?”
Draco looked so pleased with himself, Hermione had to laugh, even as she proceeded to burst his bubble. “Love, you know that’s going to get the Misuse of Muggle Artifacts called.”
“Is it though? These are magical objects, not muggle artifacts! I can’t be misusing muggle things if they’re not even muggle to begin with!”
“I—“ Hermione stopped abruptly and considered his words. “I suppose you’re right. And I guess if you just leave it somewhere, the Ministry won’t know you did it. And I highly doubt any Muggle would report such a thing to any kind of authority…”
“There you go! Look, I just want to do something nice. There’s this one Muggle mom who passes by the flat everyday with her toddler and she always looks so tired and sad, and her kid is always picking up rocks to show her. What if she got a pleasant surprise, just a little something nice?”
“That’s…really sweet of you, actually.” Hermione beamed at him and went to pick up the rock from the desk. “Maybe paint the rock more brightly, though? This brown is just…chocolate syrup?!” She quickly put the sticky lump back down and sniffed her fingers. “Draco, what on earth?”
“I, uh…couldn’t find any actual paint? And you had the syrup in your cupboard.”
“If you put this outside, it’s going to be swarming with ants and nobody in their right mind would pick it up, ever. Why don’t I just transfigure the syrup into paint,” she twirled her hand in a quick wandless, wordless charm, “and then we can find some other, better uses for chocolate syrup,” she continued with a cheeky grin.
