Health made the point that a married woman whose husband is in town has different rules than other (read married w/ husband out of town, single, etc.) women.
While I am unsure about how different, and whether this applies to therapy-like situations, the general idea is (gasp) indisputably correct.
Any argument on this point should be from someone who knows about the “baalah b’ir” concept, not ignoramuses (like myself – I don’t know much more than what I just wrote).
As an aside, because a gedolah is bchezkas nidda, single girls should not be characterized as “the kal.”
