It was Sirius’ very first day as a Ta and he was equally excited and nervous.<br/>He was walking with professor Mulligan, who was telling him about the class of four and what he was likely to expect from this experience. Mostly, Sirius was just thrilled by the prospect of getting to help other students while getting his own doctorate, knowing that it was going to look great on his resume in the future as well.<br/>He had even tried to dress properly for the occasion, his normally more messy bun now impeccably tight and proper, his shirt buttoned one button higher than he normally would and generally having made an effort into looking like the young professional professor Mulligan took him as.<br/>He just hoped that he would be able to live up to the potential the older man saw in him.
