" It is, of course, true that discrimination in trusting others is necessary if we are to have quality relationships. Selectivity is important for our safety and security, because it means trusting only those who have proven their dependability. This makes sense but only in how we love, not that we love. Thus, our ways of showing love differ according to the commitment we have to various individuals in our lives. But our scope of love does not have to set or be set by limitations. We can be careful about our boundaries when others come close but free of boundaries in how far our love extends. There are boundaries in the topography of love but no barriers. "
