Hey, I'm Alex (Alexandra) I'm 17 and this is about knowing when you're falling in love. You see, most people don't know when they are falling in love, until they're in too deep (literally). There are 12 steps to falling in love with someone, and this book tells you what they are. If you notice that you have any of these symptoms, please CONTACT UR DOCTOR ASAP. Or just tell him/her that you love them, whatever works.
