Good question, Jane. Good, informed discernment on this topic could lead to a new and better way for communicating needs and treatments in the realms of people who are experiencing distress and are interacting with others who may offer some sort of relief through the kind of compassion that is only possible when an exchange of value has occurred. (For "exchange of value" I mean when two people communicate in a way that is even--where Person A is able to say what they feel on a foundation of honesty and trust and where Person B witnesses them with clarity, minimizes the vulnerability of the situation with love and ends the exchange with a feeling that the situation has improved. Whew!)
