I think it could relate to ones sense of caring, more or less wanting to be cared for. Which comes in many forms: Friends, Family, Significant Other and so on and so fourth. If we didn't want to be cared for we would do our own thing with out regard to others approval. We all want to be cared for in some since of the word. From some one to start and build a family, or life long friends, we need to be cared for. That is just a point of view I thought id toss out there.
