What is Love?

Life is a mystery only few can figure out.
Happiness can be anything that makes you feel complete; people, places, and objects can make a person happy.
Growing up is something we all do, inevitably death follows.
What might love be?
Is love when you find yourself smiling at nothing because you thought of your special someone?
Is love when you feel protected and warm as your parent engulfs you in a hug?
What's the difference between platonic and romantic love? Is it the attraction? The anxiety? The excitement?
How do you know you're in love?
How do you make love last?

And how on earth is Carmen going to survive when her weird new neighbor asks her all these questions?
