Well... aaakchually.. it isss like this

First you meet. Then you argue, and fight, and then try to kill each other. You do not succeed killing each other, but you burn down your houses in the process. And see, you do not have any place to stay. So, you pull together whatever resources you have, get into a shack, and shag for a while. That is how love starts, not always, but usually! So, as you may have seen it already, it love begins with enmity.

If you were wondering what to do, go ahead and pick a fight, beat the daylights out of each other, and that definitely will lead to some good, vigorous, make-up sex. And there aint no stopping love after that. I could be wrong, but i am pretty sure that is how it goes.

However, don't try it at home.
