Remus sighed. He was used to that sulk: more than used to it. In fact he'd only started getting unused to it, but apparently a life of peace and quiet (and tea!) was not to be.

While he hated rewarding such immature behaviour, it wasn't like Sirius' hadn't had the most utterly worst day of it, so he rolled back and gently rested a warm hand on Sirius' back. "None of your bother, then," he murmured, in a tone that didn't really brook any opposition, as fond as it was firm. He surely didn't want to get into an argument about Sirius' typical placement of his backside.
