What is love?

What is love? That is an interesting question, and I'm sure that everyone has their own definition. I myself don't know the answer, as I'm still meandering through the world of love and discovering its many twists and turns, pleasures and pains... Perhaps this question is best answered in the not definition, let me explain.

The not definition is something that you use in probability or set theory. For example if you have a set A = {2, 4, 6, 8}, and this set is in S = {1, 2, 3, ..., 10}, then Not A (or A complement - if you want) = {1, 3, 5, 7, 9, 10}

So, perhaps there is no answer to this question, but there are a lot of non answers.

For example, what my friend Raoul and Rupert have, it's not love, even though Raoul claims that it is: "Yeah, it's love, because we stop fighting very fast."

By this train of reasoning, my exes didn't last with me, because it was not love, and that's because we never fought. There were times when my exes did bizarre things (like going crazy on me, and then they realized it was their fault and called to apologize, but we never had full fledge arguments).

If what Raoul and Rupert have is considered to be love... One of the following things (or possibly all of them) reflect my train of thought:

a) Count me out. I do not want this type of love where there are so many issues;
b) I don't think that love is this simplistic... It is not so formulaic... It is not P(t) = Poe^kt;
c) Love is related to the person, and not how much a couple fights. If this were the case, my parents would be the best lovers in the world... They fight all the time, and then they make up quickly so they can sleep in the same bed...

So, to wrap it all up... I think that love is different for everyone, and that there is no single definition for it... However, there are an infinite amount of not statements - i.e. love is not this, and love is not that, and what they have is not love, etc.
