When we grow up in families without boundaries, we do not learn how to establish boundaries between ourselves and others or ourselves and the world. This lack of a sense of boundaries makes us vulnerable. By the same token, it can make following rules and honoring boundaries difficult for us. So, it would make sense that T has to establish firm boundaries or else some harm could inadvertently occur to either participant in the relationship. I've just been reflecting on this boundary topic myself. Thanks for the posting.
