If somebody hates you, there is a reason for it. Normally
hate comes about when one person has hurt another person in such a deep way
that an emotional wound persists long after the deed has occurred.
If this is your case, take responsibility for your misdeed,
communicate your sorrow to the other person and ask for their forgiveness.
If they are not open to the mending of your relationship,
give it some time and then approach it again in the same way. If they still
refuse you, kick the dust from your feet and move on with your life.
You have done your work and you can move along comfortably.
If the other person continues to hate you, so what? The hate they feel and keep
alive is merely the rancid remains of past misfortunes.
Your objective is to refrain from hating them back. To love them in the truest sense of the word,
is to give them understanding, compassion and wish for their best.
