Love. Love is something that makes us the realy. We are nothing without love, so because love makes us capable of sacrifice. If we love someone, we get used to being honest and true. It is possible to say that love is causes lots of our principles. From the ancient time to the nowadays love is building a "house" of the human feelings. And this house is being built by the all people. I think love is some more, then only official union of the two persons.
