"I don't think I can do the math in my head. Do you have a bit of spare parchment?"
Lily Evans's voice rang clear through the room to James Potter. So she needed some spare parchment? He could give her some and be her hero!
Except...
He didn't have a single scrap of parchment.
"Quick, mates, I need some parchment! Hurry!"
Moony looked at him like he had lost his mind, "Do you honestly believe we packed our parchment to Hogsmeade?"
That made Sirius snigger. It wasn't often that Remus made a retort like that.
Meanwhile, Peter was digging through his pockets until he found some. He produced a tiny piece of scrap parchment like one would pull a golden chalice from their robes.
James seized it, grinning. "See, Wormtail? I knew there was a reason we kept you around."
He winked and loped off to Evans. "Hey, Evans! Did you need some parchment?"
She looked up from scribbling down numbers. "No, I found some. Thanks, though."
James went back to his mates, utterly crushed. Sirius patted his back with a grin, "Better luck next time, Prongs."
