The problem with Hogwarts was there were so many things Remus wanted to do. He'd always planned to try out for the choir and actually get on the platform at dueling club and learn to play Keeper and raise an award-winning mandrake and get enough tutoring to get through an entire potions lesson without blowing something up... By sixth year, Remus realized he needed to prioritize – there would never be enough time for everything. So he set about achieving the more manageable goals, like reading all the useful spellbooks in the Restricted Sections. Or trying to…
"Did you sign up for Extreme Lack of Social Life this term, Moons?" Sirius flopped into the chair opposite Remus in the library and lifted up the book with the tip of one finger, clearly wanting as little contact with it as possible.
Remus stifled a small smile. "I believe you say I'm taking that every term." He tried his best to go back to reading.
"Well, perhaps if you spent Sundays in bed like everyone else, then ate an enormous breakfast, and then shagged a bit…"
Remus choked. He coughed, gagged, and generally failed to regain his composure. Sirius clambered over the table and slapped him on the back.
"Bit dusty there, Moony?" he asked with clearly faked concern.
The boy in question gulped and attempted to ignore the double entendre. "Well perhaps if more people at this school read, we would have fewer dusty books to pollute the lungs of the devoted few."
Sirius arched an eyebrow. "You're just not reading the proper stuff, mate. I dare say you couldn't find a dusty copy of the latest 'Busty and Bewitched' if you tried. Unless you count the emergency copy James keeps in Filch's supply closet on the fourth floor."
"His WHAT?" Remus was very certain he had lost his mind somewhere in the cloud of dust and things-which-rhyme-with-dust.
The elder Black gave a shrug. "Sometimes you need a safe place for things. For instance, I know my box of 'special toys' is-"
Remus spluttered loudly enough to earn a glare from the librarian. "This is a LIBRARY!" he hissed.
"Yes. Where one researches things for end-of-term papers and others copy his work. So, do tell, what class requires you to know ancient spells in April?"
"It's never too early to get started," said Remus, adjusting his collar and attempting to look Very Responsible.
"Which class?" pried Sirius simply.
"I… er… well," he stumbled, "what I mean to say is that…"
"You're wasting your free time in here with this instead of outside with me?"
Remus had very little to say to that. "I didn't know I had another option," he said defiantly while gently closing the large book.
"Silly Moony," laughed Sirius, reaching out his hand. "Shall we?"
And so it went, every time Remus tried to make it back to the book. Until, finally, he stopped trying and lay in bed on Sunday mornings until Sirius woke up and began pulling at him to go eat a giant breakfast before they began that day's adventures.
And they were very nice, pleasant adventures. Some of which involved snogging in corridors and others of which involved sneaking into Hogsmeade for all manner of illicit things. It was fun and they did it together and that was what mattered. He could always do the other things later.
