Remus chose not to respond further regarding Muggle fashion. While he was fascinated with the non-Wizarding world, he realized others might not feel that way. Particularly certain Purebloods. "Understandably. It's a good place to start, knowing yourself. Or so I'm told."
He opened his mouth to reply to the next question, then closed it again and thought it over for a moment. "I'm not sure, actually. But, it's nice. Maybe I've grown used to expecting the negative from those I'm not close to over the last few years." It was the truth. Remus had often been able to shrug it off, but he had to admit that expecting something made it somewhat easier to tolerate when he was turned away from jobs or looked upon with suspicion.
His brows raised in surprise when Regulus seemed to accept the offer. He did not regret it. Quite the contrary, he was glad for it, but he hadn't really expected the younger man to even consider the opportunity. "I promise you, it's not. I'm pretty sure Sirius will hunt me down when he finds out." Remus grinned. "Older is probably better. Maybe even start with my seven years, those who are looking for something more advanced for their NEWTs. I'll have to clear it with Dumbledore, of course, but I think he wouldn't mind. As long as we're teaching them to defend themselves."
