It's so short that the average reader could probably finish reading in just about half a minute. This was based on something that happened to me, sort of. One-shot plot bunny, and definitely OOC. I don't own anything.
Noses
Harry, Ron, and Hermione sat in the library. Hermione reading a book with fascination, and the boys just sitting there playing rock, paper, scissors with each other while waiting for Hermione.
"I just read something interesting. Did you know that without using magic, a person cannot see his or her armpit directly with both eyes at the same time? It's because your nose blocks one eye's line of vision," said Hermione.
"No way," replied Ron. Then he started staring at his armpit, slowly and simultaneously blinking his eyes and twisting his head at odd angles.
Harry disagreed. "It isn't true for everybody. Voldemort could probably see his armpit, because he has no nose."
Yes, I know that it isn't realistic and super short. But it's just a little idea. Don't think about it too much. Review!
