Definition: 'Love' is making a shot to the knees of a target 120 kilometers away using an Aratech sniper rifle with a tri-light scope.
Statement: This definition, I am told, is subject to interpretation. Obviously, love is a matter of odds. Not many meatbags could make such a shot, and fewer would derive love from it. Yet for me, love is knowing your target, putting them in your targeting reticle, and together, achieving a singular purpose, against statistically long odds.

On a more serious note, it's honestly rather hard to describe love in and of itself (Though TIHH put it rather nicely). You can think you know what it is, and be wrong. But in the end, you'll know it when you feel it.
It feels a lot like infatuation, but it has something else to it that's hard to explain. It manifests differently from person to person, so it's a pretty subjectively defined concept. In my case, I see it as a realization of a complement to your persona, a discovery of the missing piece, if you will.
For example, the woman I still proclaim to be my true love is an energetic and outgoing person, whereas I'm calm and introverted. Our other aspects mesh, and so our opposing sides, instead of clashing, balance each other out. She makes me cheery and energetic when I would normally be cynical and self-absorbed, and I'm able to calm her and provide a more balanced view of things. All in all, not a single serious argument has been had between us in the three years we've known each other. It's a truly wonderful feeling, but it's hard to understand from words alone.
