Genieve has offered up a couple of ideas, but in the interests of fairness, I'm just going to take one: "I am responsible for you, all of you. I feed you and I clothe you and I give you shelter."
I'm a very independent person. I can look after myself. I don't feel like anyone has given me shelter or fed me - in the immortal words of Beyonce, 'I depend on me.'
But as I take the longer view, as I appreciate the length of life and the origin of my independence. It is, of course, a fallacy. I don't depend on healthcare because I was raised free of disease and accident. I can work for myself because I was given a fine education. I am not in my decrepitude as I hit my late 30s because I was born in an era when life expectancies are long. My freedom was given to me long ago and given so freely that I barely acknowledged it.
It becomes more valued every day. Not everyone is so lucky. I wish the world could have what my parents have given me, and what their parents gave to them. And I suspect Genieve is intimating something similar.
