Remus’ question made Sirius laugh.<br/>He knew that that probably wasn’t the reaction that Remus had been hoping for, but he knew that the reason for his nickname was stupid and thus he felt stupid for answering. It also served to show just how long they had been out of touch with each other, because Sirius knew that his doctorate was certain to come as a surprise to his old friend.<br/>It wasn’t that Sirius was ever super booksmart, nor that he cared too much about being good at school, but once he had gotten a safe home base, he had found that he was actually good at it. Good enough at it that he had decided to get a doctorate that he didn’t use.<br/>“It’s a weird story,” he said with a warm smile, not sure it really was, but he found that he had no other way to preface this. “Long story short, it’s because the guys realised that I have a doctorate in mechanical engineering.”
