+When you wake up, and they're you're the first thought and you're looking at your phone to see if they've text or called you while you were asleep. And when you go to bed, you fall asleep thinking about them. When you miss them, even though it hasn't been more than a day or so since you've last seen them. But mostly, when you put their needs before your own. When their happiness is more important than your pain. When you really love someone you're willing to give it your all, and you'll know when you are.
