We’re All Restaurants: Treating Emotional Responsibility Like Allergies

In order to understand healthy emotional responsibility, I've come to adopt the attitude of treating one's own emotions & the emotions of others, like allergies. In any relationship: be it with lovers, friends, family or colleagues, there's often a question around emotional responsibility. In dealing with one's own and others emotions, what is reasonable & responsible behaviour? What am I supposed to take care of, what should I share and what should I expect from others? What behaviour should I promote, what should I tolerate and what should I avoid? When should I listen to my own emotions and act on it and when should I take a step back?
