Remus took the bottle, staring at it for a long moment. He had his options, as always. He could refuse, as usual, but that would get Sirius' spirits down. Or, he could partake and enjoy himself with the rest of his mates. Both decisions had their pros and their cons, but nothing could outweigh making Sirius happy, not for him. With Sirius close by, it couldn't possibly be that bad.
Putting on a smile, Remus looked over at Sirius and brought the bottle to his lips. "Cheers," he muttered, tipping the bottle back and taking a long drink. He could afford one night of typical teenage recklessness.
