Remus shook his head gravely. "It's worth a shot. I don't want anyone to know I'm a werewolf who doesn't need to know. It'll only scare them."
James looked up from the half-finished Potions essay sitting in his lap. "I don't think Evans would be too bothered. You needn't make too much of a sweat." his eyes flicked towards the essay again, and his mouth twisted in exasperation. "Pfft. I give. Want to go play Quidditch, Padfoot?" he pushed aside his homework as he and Sirius raced for the portrait hole.
"You really should finish that-"
Too late. They were gone. Remus leant back in his chair and looked over his letter. He didn't think he had enough energy to improve it. The full moon was merely 5 days away, and his strength was drained. This would have to do.
Even with his 3 best friends, tonight, Remus felt more alone than ever.
