"Well, as far as I know, Professor, I am not a werewolf. I have never made that dreaded change that plagued my famous uncle. And, yes, he did train me very well in DADA matters before I came to Hogwarts years ago. However, I think you would find me quite useful to your muggle studies. I was raise, and still live, in a muggle community in Cornwall. The Lupin family farm is there in a remote rural area just outside a fishing village on the coast. My father is a potionsmaster and he works at the local apothecary. He dispenses medications to muggles as a muggle pharmacist, but he also formulates and sells potions to the magical folk who live there.
"You see, we have as many magical folk as we do muggles, and we have been able to keep our magical folk secret for generations. I grew up knowing the muggle world as well as I do my own. I even own a muggle car that I use when getting around the muggle community so I can blend in. I would think a witch who is equally comfortable around muggles as she is around her own kind might be of value to you. And, as I said, I believe our young students underestimate how important it is going to be for them to understand muggles, as close as our communities are becoming. "
