Dear Professor McGonagall,
I saw a cat sitting outside my Muggle family home the other day… was that you? I was studying my spells, and labeling some new bottles for potions.
P.s. my dog got a hold of my acceptance letter while I was out at the store, she tore it up! Is there any way I can get a replacement? I was going to frame it…
Dear Ms. Wood,
Why ever would I be sitting outside your home?
I am pleased to hear you have been studying outside of school. Mind the Statute of Secrecy.
It is not our practice to provide duplicate letters of acceptance. Perhaps a reconstitution spell? In other words, dear, train your familiar to better habits – before you arrive at school. “My dog ate my homework” may pass in Muggle schools, but I assure you, it will not save you from detention at Hogwarts.
