What did she do? Complain that the "husband" didn't give her a drink. SHE was supposed to be greeting the guests as they arrived and serving them (possibly asking the "husband" to help her make/carry drinks).
She acted as if the party was in her honor and not the other way around.
There was something awfully strange about the California family. The children were zombies. Did the little girl ever move from the couch? The dad was downright grotesque....he seemed far removed from his children. They may have had the money but the "poor" family certainly had the love.
