Living Out. Everything that playwright Lisa Loomer says about the blindness of the middle class -- even the kindest and most liberal-minded among them -- to the problems of the people who work for them is true and desperately needs saying. She explores these issues through the relationship between Ana, a Salvadoran nanny, and her employer, Nancy, a high-powered entertainment lawyer married to a public defender. Nancy knows nothing about the life Ana has fled, and she harbors many of the usual stereotypes about Latinos. But she's a decent enough sort, and the play raises the possibility that a real friendship might develop between these women. The beginning of Living Out can be funny, and Loomer's points are worth making -- but argument isn't drama, and the characters seem to have been created solely as the playwright's mouthpieces. We've met affluent liberals like Nancy and her husband before, and a lot of the dialogue is at a sitcom level. As for Ana, she's purely sad and saintly. Like the dialogue, the direction lacks urgency and the action feels slow.
