Mr. Ioannidis
A self-centered man who always has to be right. Is a teacher, gives daily lectures about how students these days are spoon-fed til' they leave for college. Constantly tells students how incompetent and dumb they are. Is a super old, short, grumpy man with no respect for anyone but himself. Every school has at least one Mr.Ioannidis.
Mr. Ioannidis is yelling at the foreign exchange student.
