To quote a genius: "It all boils down to there currently being no understanding of what exactly induces "love" (although certain patterns of chemicals can be spotted as a consequence of it; not necessarily the cause), and so, it remains a subjective experience due to lack of understanding of the phenomenon, and therefore, stating that it "cannot happen" based on incomplete premises is faulty logic."
Hayduke - if you believe a 'perfect mate' exists, how does one know if they have been found, and how do you understand yourself 'completely enough'?
