It must be true. When I was younger it happened ALL the time. Just not always for a long time. But who says that the key element of love is it's duration? Is there any reason that the feeling of something perfect and new and exciting fails to meet the definition of love? If the definition requires that it there only be one love and that it last a lifetime, then you'll never know whether or not you experienced love until you die. That's a ridiculous standard to hold someone to and can only result in a life of disappointment and misery. And what the hell would the point of that be?
