It was Sirius’ birthday only a few days after Halloween. All of their friends knew not to make a big deal out of it, though. It was a  thing  that Sirius had, like some kind of birthday-specific melancholy. Some of it was probably because of the horrific birthdays they had as a child that were more about pandering to political allies than about Sirius. But also, it was because they didn’t like aging.
