After any unfortunate event, you will be in bondage to the situation until you forgive. When you hold a grudge, you will begin to experience resentment. The person(s) involved may not deserve your forgiveness, but you deserve peace. Think about letting it “all” go so you may live in the present.
And soon, you will master maturity. How? A time may come when you have an opportunity to take the person down but instead you walk away.
