The credibility of this article goes to family discussion. The interesting part is we all talk about love and cohesiveness.
However we forget a very simple rule in physics and the interesting part is its completely applicable. If one has an affinity to an individual on some level there will be a repulsion and the participating parties in the said relationship has to offset the repulsion there by creating a simpler bond and thus proving that caring too much is a waste of time. It will create negativity, so indifference is the best policy.
Just a thought.
