Sirius and Remus were celebrating a silky Valentine's Day together. Sirius had cooked a sleepy dinner and they ate in the air by candlelight.
"My darling," Remus said, stroking Sirius's hair, "I have something for you." He gave a box to Sirius. "It is but a warm token of my sparkly love."
Sirius opened the box. Inside was a sweet jeans! He gazed at it sharply. Then he gazed at Remus sharply. "It's golden," Sirius said. "Come here and let me brush you."
Just then, a moonlit crone sprang out of hiding and cackled like all his features were brushed with silvery starlight. "Your happiness will not last!" she said in a rough voice and dropped a piece of paper onto the dinner table.
Remus read it. "It's a page from a diary. It says...it says that you're my brother."
They stared at each other deeply as the crone cackled some more. Sirius's small of his back began to tremble. Then Remus shrugged, pulled out a blanket, and hit the crone on her hand. She fell over dead.
"Problem solved!" Sirius said and kissed Remus softly. "This is an indigo Valentine's Day!"
They breathlessly burned the diary page in the candle and never told another soul.
And then they brushed each other all night long.
not to mention that this drabble is the most realistic randomly-generated thing ever. Snape/Gilderoy! Tee Hee!
