I don't think familial bonds count in unconditional love.

I see what you are saying, but there is a basis for the concept of caring. What does it really mean? We can say we want "the best" for a person, but when thoughts become actions how does that translate?

I think there are too many answers to really quantify it. I think the word "empathy" would apply. Their pain becomes your pain. Their joy becomes your joy. Beyond that I'm not sure.

I've always wondered where such an empathic 'chain' begins. For example, in a situation where you are maybe feeling decent and then you come in to contact with someone who has pain and then from empathy you might get or experience the pain, however, I wonder, why isn't it that they instead feel better or decent? How is one supposed to cope with continuously experiencing not just their own joys and pains but also those of all those around them?
