What is love?

Sometimes I hear people say 'Love is all that counts, love is everything'This made me thinking. I always thought those people were stupid romanticists. I mean there's so much more in life, than only love. I may not have a boyfriend, but I'm perfectly happy. But than I asked myself What exactly is love? Is there a defenition for, or is it just something abstract, a feeling? Is it only attraction and passion, or also love for a friend? Or maybe even for a dog? Can you only feel love for someone, someone who can answer your love? Or can you also love a place, a sport, or a song? Can you love a day, an evening or a day? These things brought me in a huge frame of thoughts. What exactly is love? And finally I realized all those people were right. Love is everything and beside that Everything is love.
