At first, when Ira heard the great wizard's name, Chauncey Oldridge, she felt it was really funny! Who keeps names like that?
She had no idea who he was. Listening to others answers, she gathered that he was a victim of Dragon Pox..Well another variation of muggles' Chicken Pox! Oh no no! Vice Versa! Maybe muggles named Chicken Pox after Dragon Pox...
Before Hogwarts she hadn't thought about influence of wizarding world on muggle world...But now listening to professor, she felt as if almost everything was taken from wizarding world!
