A crucial bit Philosophical question:

Why don't you give your definition first which then can be discussed by the community?

I think that I would go with Jesus on the definition of "real love" that no one has greater love than the one that would sacrifice his life for others as he did for us. So, I guess real love would be giving to another person what they need at the time and so it could as little as giving something to drink to one that is thirsty.

I wonder sometimes why we feel a need to qualify or quantify love like it's a commodity or something. I feel love is one of the rare qualities in life that can not be measured. I think the question in most cases is, what do you define as love? Looking at the quote you provided, it looks easily understood and sensible. But is it? What you sacrifice or refuse for the sake of others is as much an intellectual decision as an emotional one. We know this because just looking at our children, what we sacrifice will almost change as years go by. When children are of the age where they can not fend for themselves, we make many sacrifices to aid, them, feed, clothe and many other things that allow our child to grow and mature in the healthiest of ways. Once they get older, what we are willing to sacrifice will change because at some point that child is suppose to be able to fend for themselves. We might have walked away from opportunities to travel and enjoy ourselves when the kids were adolescents, but more likely to take these opportunities once those same kids are in their 20's. Most of our decisions on how, why and what is acceptable in the area in means of caring for another human being are centered and based in need and then prioritized by connection and unfortunately, influenced also by how others perceive our actions. Most people are very much like this ... a person may have child, parent, sibling, significant other and/or best friend ... all of whom suffer the same affliction ... all of whom need the same level of care ... do we really care for them the same, or is it more likely that we prioritize this need of care and apply ourselves accordingly. Does this mean we love them any less or more? I do not believe in a concept that attempts to measure love.
