What is love?

Love is a fire. It can do just as much bad as it can good. Love is a knife. It can be used to hurt people, and what seems shiny and useful may actually be more dangerous and harmful than you think. Love is a car. It can't work without a driver. Love is a dentist. It's very needed, useful, and even enjoyable when you're told what you want to hear, but very painful when you're told something you're not expecting. Love is cake. It's so sweet but you can only have so much of it, too much of it can be unhealthy.
