Forgiveness is an act of letting go of a wrong deed done to a person. To some people, forgiving is so hard, while some forgiveness happens too easily

It's actually not easy to forgive, as you already said it's complicated for some people to forgive and let it go but it's a different thing to some people because they handle forgiveness so easily. Of course people aren't the same and it doesn't matter how long it takes to forgive, what counts is that we all need to forgive and move on. Forgiveness is a state of happiness and laughter, where there's forgiveness there's happiness and laughter at the corner. The best thing about forgiveness is that we earn compensation from God because he forgive us when we forgive our fellow humans being. Best of luck bro.
