How do you know when you are in one. Do you just let things happen like come what may and when certain things happen you assume that means you are in a relationship? Or do you sit down with the person and clearly define the terms of service--explicitly and mutually uttering the words "We are in a relationship. You are my man/woman." Is it even necessary to put a label on the time we spend with someone or can we just enjoy the person without the pressure of expectations. And if we do that is the person anything more than a ***** buddy. Isn't it a matter of respect and true compassion to clearly define one's intentions?
