"All right," Severus answered with a nod, before taking a deep breath and stepping forward just enough to catch her in a hug. "But for the record," he added quietly, close to her ear. "The offer of my shoulder is still available any time you wish to take advantage of it." Then he pulled back, smirking just a little. "Provided there are no surprise massages involved, that is."
Of course, he'd meant it as a joke, but in reality, he was only half-teasing with that comment. The only thing he liked less than being touched, as a rule, was being surprised with some sort of touch. It usually wasn't a problem, because most people thought he was thoroughly disgusting, but Lily didn't, and he could only just imagine her trying to sneak up behind him and rub his shoulders, only for him to flinch and for her to get the wrong idea entirely. But hopefully, with that 'teasing' warning, she might realize it wasn't a good idea.
