Severus Snape loved teaching at Hogwarts. Oh, he may have loathed most of the bumbling idiots in his classroom, but he loved the position of authority being a teacher gave him over them. He loved having an excuse to make others' lives miserable, if only for the short period of time they spent in his domain. He loved inflicting even a fraction of the unhappiness he endured daily. But lately Severus loved pestering Harry Potter, the famous Boy Who Lived, most of all. Loved to watch the passion of anger enter his eyes, watch his jaw lock to prevent a witty retort that would only land him in more trouble. Severus loved that he could inflict these pains on Harry so that they had something in common, something between them, when they could share nothing more. Yes, Severus Snape loved teaching at Hogwarts.
