Read the following article and select the best answer. Article: Kids may need to apologize if they do something they know was wrong-like telling a lie or breaking a rule on purpose. When they do something their parents tell them not to do, or they don't do something they are supposed to do, they apologize, too. Grown-ups can apologize,too,to other grown-ups or even to kids. After all,even grown-ups make mistakes sometimes. By apologizing when they're wrong,grown-ups can set a good example and show kids how to do the right thing and apologize when they need to. Saying I'm sorry when you need to is the right thing to do. It does a lot of good. But by itself, _ might not be enough to make everything all better again. Sometimes along with an apology,a person needs to fix the mistake or promise to do better. Sometimes doing a nice thing for the person after you apologize helps show that you really are sorry and want to be friendly again. Sometimes a heartfelt "I'm" sorry fixes everything right away. Other times,it might take a while for someone to feel friendly after you apologize. You might need to give the other person some time. Even after you say you're sorry,you might still feel bad about what you said or did-but you can feel good about apologizing and about making up your mind to do better. When someone apologizes to you,you might not feel like being friendly again right away. Once in a while,if a person doesn't change,you might not want to be friends anymore. You might feel glad that the other person apologized and admitted being wrong. But if someone keeps behaving in mean ways or does something that keeps hurting,you might not feel the same way anymore. Just because someone apologizes to you doesn't mean you have to be friendly again. That part is up to you.
