“ ..what moved me was that I had found something I didn't think could exist. And that thing - the thing that I found - was very simple. Most people know all about it and have never really doubted it because their lives have been such as to give them a glimpse of the thing that they were not sure about, which is love, of course: the sheer fact of feeling of love for another, of finding the one person - the only person, it seems - who makes the world make sense. It's like discovering the map that you've been looking for all your life and have never been able to find - the map that makes sense of the journey. ”
