Learning remorse at wrongdoing is tough, especially for children. However, having a few little words to help show that remorse can really speed the process of making up for saying mean things, not sharing, or being rude. Readers see the many situations in which the words "I’m sorry" should be used, including scenarios they may encounter in school or at home. Understandable language helps introduce this important concept and explains how much better everyone feels when an apology is given.
