frevelm,
Yes, it is a safe assumption that the normal family structure is almost a necessity. While "normal" for me is somewhat different from my original family structure, the basic structure "faith" was in place during my early years of life. What is "normal" for someone else will have it's own uniqueness. I may or may not agree with their "normal" due to my own socialization.
Having said that, I have "fine tuned" myself into a model which I feel works well for my family and self, in addition to those associated with me. Since life and the world around us changes daily, I need to keep myself "fine tuned"...healthy, balanced, prepared, listening, questioning, thinking, studying, mentoring, leading and living a healthy lifestyle by setting the example.
What we DO matters. It can influence others. If we think it does not, it is because we are still learning ourselves and aren't ready to teach or lead. 
Many Blessings in ALL YOU DO,
