Well, but we as clients do not necessarily act in a usual way with our therapists. We are actually "allowed" to break social rules because it is assumed that we need help with difficult issues that keep us suffering and having symptoms that include not knowing about boundaries or social rules that govern relationships. It doesn't mean it's okay in the sense of being healthy, but it is okay in the sense that the therapist is supposed to expect and tolerate things like acting out or intensity.
