I think most people, especially young since they're new to these feelings, mistake a crush for love. A crush is when you think about that person, you're interested in them, they have qualities you admire. Love is when its much more intense; you understand the other person like you understand yourself, yet both people feel like they can learn from each other. They're willing to build something together, whether its themselves, or a family. Anyone at any age can experience this; its just a matter of luck, fate, coincidence, or however you choose to believe in the occurance of small wonders.
