Why is love so good...? You love someone and they leave. They come home one day and you say "What's happening?" and they say, "I got a better offer someplace else," and there they go, out of your life forever, and after that until you're dead you're carrying around this huge hunk of love with no one to give it to. And if you do find someone to give it to, the same thing happens all over.
