The dialogue in the memory is from Harry Potter and the Sorcerer's Stone, pages 14-15.
I'm writing a fanfic of a fantasy series, and I have to draw a motorcycle? DAMN YOU, J.K. ROWLING!
On a more serious note, look at the way Hagrid refers to “muggles” as “swarming around” – I think it's rather dehumanizing. If I lived in this world, I'd probably be careful to use the phrase “non-magical people” instead, because “muggles” is used in a dehumanizing way so much.
I'd kind of like to have a different term to use in these annotations, too, because “witch/wizard” is gendered. (As a side note, I insist that in general usage, “wizard” is gender-neutral. The main reason I insist upon that is because I enjoy claiming to be a wizard even though I'm not male, but it does have the support of some existing authorities, such as Dungeons & Dragons. However, this is a Harry Potter fanfic, and in the Harry Potter universe, “wizard” is definitely gendered.)
