Others show kindness to you so that you can remember that you are friends, friends in times of adversity and hardship. Mutual help does not need to be repaid. If you repay them, the relationship between you will be better. Wouldn't it be a matter of reconciliation, and wouldn't friendship become dull? Of course you will never forget those who have hurt you. People will also retaliate instinctively, but it depends on how you retaliate. Make yourself stronger, live your own life, and let him see it. This is the best revenge. .
