She knows the Heimlich she won't choke, not Daphne (farsick) wrote in caged,
Re: 7th Years Reactions
Daphne would have stood and introduced herself pleasantly, with a small smile, when Alecto got to her.
When it came to sharing knowledge of Muggles, it would have been apparent that she is rather lacking. After a few moments of looking as if she was casting about for a few paltry factoids, she would have offered that she recently heard that they have machines called..."probes"?...that they have put into outer space to try to study the planets.
This would have led her to remember and share that Muggles also have large, noisy, dangerous flying machines that they use to travel long distances because they lack the magic that makes much safer options such as Floo, Apparition, and Portkey travel possible.
