Nobody owes you an apology.
Sometimes the reason people would decide to apologise to you is because you are a person with much ego and only knows how to hold onto grudges forever.
They only believe that having peace of mind is better than having a quarell over you, they just had to tell you sorry even when it was obvious that you were wrong.
People would give up being right because you yourself has already given up the ability of thinking of the long-term benefit.
Don't be egocentric, learn to understand people and don't be selfish.
