"C'mon, Lils! It's fun! You should know, it's a muggle invention!" James tugged at his girlfriend's hand, trying to drag her out of the library to come and try his new game.
"James, it's pouring with rain!" she moaned.
"That's what makes it fun!" he pulled relentlessly at her arm. "And if you're that worried, you can always cast an Impervius charm on yourself! Please?" he pouted, widening his hazel eyes in a way she couldn't resist.
"You shouldn't be allowed to do that," she grumbled. "Not fair."
"You do the same to me," he pointed out happily, finally succeeding in pulling her along after him.
"I'm a girl. It's different."
"There are no double standards here, Lilykins. We are a partnership of equals. C'mon, loosen up!" he grinned.
"So you think," she muttered. Nevertheless, she ignored her better judgement, and followed James reluctantly outside into the pouring rain.
"Check it out!" James exclaimed excitedly, not caring that both his and Lily's hair had been plastered to their faces in a matter of seconds. "Slip 'n' Slide, baby!" he added an exaggerated accent for dramatic effect. A long piece of bright blue tarpaulin that Lily didn't even want to know where it came from was stretched over the flat grass near the lake. Currently, a very wet Sirius Black, surrounded by the other two Marauders, was sliding along it at a very high speed wearing nothing on his feet but very damp socks. His arms flailed out beside him as he tried to keep his balance.
"Flaarrgghheenhaarrf!" he screeched unintelligibly as his face plummeted into the mushy grass.
"Yum. Grass," James commented, while Lily doubled over laughing next to him.
"Oh, for Merlin's sake!" she giggled when she'd almost sobered up. "Let's go!" She tugged off her black ballet pumps, and pulled James through the muddy, sloshy stuff underfoot towards the tarp, gaining speed as she went. When she got close enough to it, she dived forward onto her stomach, and slid across the material similar to a penguin on an iceberg, soaking her robes, but laughing hysterically like a mad woman.
James followed suit, but accidentally crashed headfirst into Lily who was in a giggling heap near the end. Rain pouring down her face, she reached down to gently grab James' face with her delicate hands, and tilted his head upwards to face her. She leaned down, and kissed him slowly, revelling in the cheesy cliché of kissing in the rain, and not caring what any one else thought.
Especially not the Marauders (i.e. Sirius), who were catcalling a few metres away.
