HUH! What is it good for...
Love is an evolutionary construct designed to ensure that the female of the species would have a partner to allow offspring to survive. As the our ancestors began walking upright and their brains began enlarging, they evolved an interesting way of allowing continued cranial expansion. The birthing of immature young. This meant that for years, the offspring were unable not only to fend for themselves but also unable to walk or communicate. "Love" is the way evolution solved the problem of males running off and pounding ass all day, never to be seen again.
Then Disney got a hold of it, and fooled entire modern generations into believing it was out there for everyone and there was such a thing as "one true love". Love is scary, it's like a drug you can't turn off and a loss of control that outweighs any insanity or derangement.
But damn, like all drugs, it feels GOOD!
