When you do something and find yourself doing something wrong, the first thing to do is to stop making mistakes, so as to reduce the consequences of doing something wrong. You must not be impulsive and make mistakes again. Secondly, you should sincerely apologize to the person who has been hurt by yourself and express your guilt to him in exchange for his forgiveness. Remember, your attitude must be sincere, so that others can feel your sincerity. It is not terrible to be wrong, but to be afraid of not repenting.
