Teenage Love; Puppy love or the Real deal?

Many of us have had a boyfriend/girlfriend relationship right? And most of us have said," I love you" to that person right. When you said it did you mean " im in love with you," or "i love you" because honestly there is a big difference. Love, by deffinition is a strong word. Why do we use it so freely? is it because our ignorance as teens make us want to believe that we actually are in love, or is it somewhere in the back of our minds we believe we are in love. i am not saying as a teenager, we are incapable of being in love. that is arrogant to say. but can really, what percentage of us really mean what we say. We think before speaking and therefore not only mean "i love you" but if you tell some one your IN love with them then we mean it. I am part of a small percentage that does this. Before i speak with strong words (I.E: Hate, Love, Die) I think about the meanings. if i Love you, then i will say that. but if i dont. and i only like you , thats what i am going to say. i wish the whole world would do things like that. It would save many people heart break. and save so many marriages. why is it impossible for us to say what is truly on our minds, if we are taught that it is morally repugnant to lie, then why not tell the whole truth, is it not the same as telling a lie?
