what is love?

if you are as old as i am you probably remember the 1970 movie "love story" starring ryan o'neal and ali macgraw. a famous phrase arose to become one of the top 20 movie quotes of all-time, "love means never having to say you're sorry". a story of young love against parental wishes and ending in death of a loved one. while it sounded pretty cheesy back then, there is a certain reality to that phrase. unconditional love requires no apologies does it? when we makes mistakes, the love God gives forgives without hesitation, without explanation, without consideration - it just does. this thing called love is complicated yet simple. we humans probably make it more difficult than it is meant to be. what is love?
