Mr. Scamander,

Good afternoon. I am writing today to express my utmost regret at our limited acquaintance. You see, though you are married to my dear sister and a father to my charming nephew*, you and I have seen one another so few times that it might be counted on one hand. I do not know how the Scamander does things, sir, but we Frasers honour the tight bonds of family.

To this end, I extend an invitation. As you surely know, I shall return to Hogwarts in September, and as you may recall, each return to school brings with it the need for new supplies. I should so love it if you would consent to accompany me this year, so that we might come to know one another as siblings ought to. I should so dearly love to look on you as a true brother, and it should put my mind and my heart at ease to better understand the family into which darling Astrild has married into.

With hopes for a swift and favourable reply,

Your new sister,
