Its a pretty interesting question and while browsing the net i came across some very interesting comments

Love and Hate is probably the most complex relationship of emotions that exists,. How can you love if you dont know what hate feels like, and how can you hate if you have never loved?

Love is so much closer to hate than you think.. You really have to work at love hate just happen

Just like what osho said in the video that i posted sometime ago, Love and hate are the two sides of the same coin. True indeed.
