Fuck all the movies, fuck all the stupid stories behind it, fuck everything you know about it for a second.
Think back on your life.
Try to remember a moment when you loved or came close to loving. It shouldn't necessarily be a person. It may be a thing too. Or maybe an animal.
Think about what comes to your mind when you think of the word Love.
Got something? Clear the image. Throw away all the unneeded stuff. Imagine a single thing which is the ultimate relation between the word Love and what your mind.
...Feels kinda nice, doesn't it?
