I don't have a profound definition of what I think love is; it is truly indescribable. But I what I do know is how it looks, how it smells, and how it feels. It is a feeling that is comparable to nothing else. So even if you think you have never experienced love before, I can confidently say, that once you feel it, you'll know.
I think everyone of us has their own definition of what love means to them. If you can describe your feelings about what it means to you, I'd love to hear it! Don't worry about getting too mushy, it's all love here :).
Happy Valentines Day!!
