Every character -- including the therapist -- is flawed and morally ambiguous. As a result, there are no clear-cut role models. Self-destructive behaviors (from lying to adultery) are discussed in each episode.
Most of the "action" involves two people sitting down and talking. But conversations occasionally mention violent acts, including teen suicide and an overseas bombing that killed a group of schoolchildren.
Sex isn't part of every episode, but a few characters do discuss it graphically. One woman, for example, describes a sexual encounter she had with a stranger in a bathroom stall. The same woman confesses she has sexual feelings for her therapist.
Explicit language (like "f--k" and "motherf--ker") isn't used constantly, but a few characters do use it liberally -- and it's not bleeped.
Drinking, Drugs & Smoking
A few adult characters mention drinking to excess, but they aren't shown doing it.
