Love and hate are two sides of a mirror, they are often so close to each other that it is hard to see where their boundaries are.
If you hate him so much, then chances are that you are deeply in love with him, or you have once loved him so much. If you love him deeply, then you, probably, have put yourself in a position which makes you hate him easily.
The ancient people said that a hedge between keeps friendship green, and this is a warning to those who are involved in an intertwined situation of love and hate. However, how can those who keep friendship green understand the love of Romeo, which is a dedicating love, Ann. Dolnad, the cradle-snatcher' love and friendship, and Don Quixote, the idealistic love, described in the great works of literature? They will never get to the ecstasy state of mind.
The life for people who are struggling in love and hate is, as if experiencing through the sunshine and rainstorms; the life for those whose friends are kept green is, as if the steadily mountains in distance and moving light clouds in the sky.
