Love is a word that doesn't really stand for any one thing. Words such as cat, run, sticky... they all have the same definitions for one person as they do for another (or at least similar). Love, I feel, is the only word that is defined by each person. My idea of love will be different than yours. On top of that. As we go on in life, our own definitions of the word will change. This ambiguity is why love is so hard to define.
