An arrogant, entitled elitist. This is a high-end, expensive school and the dance was at the Ritz hotel. This may turn out to be a rich man's disease as the girl had been in school in Italy and the dad, KNOWING ON THURSDAY that he was supposed to stay at home, decided he was smarter than anyone else.
"Ass****" doesn't begin to describe the self-referential arrogance of this blow-heart idiot. Maybe just being poor and staying home with no travel or big social events on your calendar will be the things that save your health or life.
