It was early, that much Sirius was certain of - and while he wouldn't have ever claimed to be the sort of person who let himself sleep the day away, he was not at all the kind of person who was eager to wake at any hour of the day. So to be awoken by a voice in his room was already setting the day off to a poor start and then to find that it was none other than Severus Snape - well today was just going to have to be a write off as far as he was concerned.
"Yes, I'm sure that's exactly the way to fix this." He leveled a look at Severus not at all pleased at this sudden change. He'd been avoiding Regulus mostly since their failed attempt at a reunion, and he hadn't even bothered interacting with Snape yet. He knew better and sure everyone told him that Severus was meant to be some kind of hero, but that didn't mean he had any interest in interacting with him at all. "Why don't you just say no a little more. If you do it enough we'll get sent back to where we belong."
He was annoyed and suddenly trapped in his room with the last person on earth he wanted to be alone with.
