Respect comes after the initial sensitivty. It's choosing the reaction to your newfound knowledge. It's making the decision to do something with it and to respond. It's possible to be sensitive to something and still disrespect or disregard that sensitivity. These are the times that people will act in spite of another person's mood or when you ignore your own body's signals or symptoms. Sensitivity doesn't determine a reaction, but it can help to guide one. Knowing how to respond is usually intuitive for most people, simply for the fact that we are conditioned to be on the lookout for certain conditions and to meet them in certain ways - seeing and comforting a crying person is sensitive, but it is not truly sensitive so much as it is encountering a situation we're prepared for. Sensitivity must be a far more adaptable and versatile substance than simply being something that happens every once in a while.
There is never such a thing as too much sensitivity. There can be too much of a response or too much disregard of the implications that sensitivity brings, but there's never too much of sensitivity itself. The more sensitive one is, the more reactive and proactive the mind and body will be in any given situation. One fully in touch with his or her body will be infinitely more responsive to danger and far more likely to survive a dangerous situation than someone without a honed sense of awareness. Being conscious of the situation gives clues to how to get through it, it unlocks the door to more possibilities. Sensitivity is knowing. And knowledge is power.
