While personal independence and self-reliance is a good thing, we live in a society that requires interdependency and cooperation. Children and the elderly are dependent based on the very nature of their situation. Physical and emotional vulnerability is a reality that confronts us all at the beginning and end of our lives. In addition, many close adult and professional relationships are co-dependent because we need other people to both experience life fully and get things done. You can’t just flip a switch and expect it to be there.
