Love and Value are two different things. Love is hot like the sun, but like the sun it can be cooled by clouds, by distance, or even a small rotational adjustment of a body.
Value though is deeper. Value is the about the goodness we see in someone, the respect we have for their talents and abilities, the importance we find in who a person is in the deepest parts of their Soul. It is easy for love to have highs and love, but when we really value someone, that is something that will slowly grow the more we know them and the more we see who they really are at the purest levels of their Creation.
