|First off, I'm not just saying this because I'm a fellow Slytherin; Good short story. I love that you gave the character's description (and wand type) first. it gives the reader a better image of Rin Chatex before the story even starts. [I knew a Scurrilous Chatex when I attended Hogwarts; no relation I assume; but I digress...]. I love that she communicates in Sigh Language, that is very original for Potterlore.
Go through the story and make sure you are using capital and punctuation properly change the "i"s to "I"s
Capitalize Merlin and add an exclamation mark at the end of the sentence in "Oh my Merlin!" Snape said, looking at the window.
Again good story. it was short and sweet and fun to read, but watch how you use your capitals and punctuation.
