you idiot - there is a deep logic in love - its called preserving your genetic code.
A mother loves her child because the child should outlive the mother and then continue sustaining the original genetic code. It is also essential for the survival of humans as this allows a better chance to infants to survive and procreate. Same logic to love b/w boy and girl - they are both looking for their best possible partner to sire an offspring with the best available genome code. right back at ya
