What does it mean when teenagers say "i love you" to eachother, or when they tell their friends that they're so in love with so-and-so? It's not true, forever and always love, not yet, but teenage love does exist. What is it, exactly, though?
Teenage love is falling in love at a young age, possibly for the first time but not the last.
Teenage love is thinking about someone and no one else in your spare time, and fantasizing about what "should have been".
Teenage love is sometimes saying "i love you" not because you mean it, but because you know its what you should say.
