In her autobiography, Eleanor Roosevelt wrote "No one can make you feel inferior without your consent." In other (less eloquent) words, don't put up with any treatment or situation that is unendurably infra dig. The word infra dig is used in relatively casual, sometimes sarcastic contexts (e.g., "Apparently, drugstore-purchased shampoo is too infra dig for my glamorous sister - only the most expensive salon shampoos will do!"). Infra dig is a shortened version of the Latin phrase infra dignitatem, meaning "beneath dignity."
