Ariadne Gamp didn't study Muggle Studies, but it didn't stop her from bursting into Professor Frasier's classroom after lessons broke for lunch that Wednesday. She was all excited and wanted to show him what she'd received in the post - because he'd be able to explain it. She'd nearly burst out of Kesali's charms class physically to catch him.
Ariadne's father was a friend of Isaac and as a result, Harry had grown up knowing of the Muggle Studies professor, though she had to be careful to remember to address him by his proper title when he was at school. She'd not decided to study Muggle studies for completely unrelated reasons, but did regret it once in a while.
"Isaac!" She exclaimed as the last of the fifth year students left his classroom. Realising her mistake she clapped her hand over her mouth and blushed.
"Sorry! I keep doing that, I am so sorry. Professor." Glancing back to check that the other students were gone, she approached his desk with a bounce and extended one long arm with her school jumper pushed up to her elbows, offering him a postcard.
"Dad sent it to me, arrived this morning, but I don't get it, what is the photo on the front? It doesn't move so I know it's Muggle. Looks like some big metal thing. He said Muggles use it for astronomy, and it's like a bird?" She explained, referencing the photograph of a space shuttle on the front, a foreign concept to Ariadne.
