Yes, it's a bit on-the-nose. But for Yom Kippur, the Day of Atonement in Judaism (this year starting October 4 at sundown), read Sorry, Sorry, Sorry: The Case for Good Apologies by Marjorie Ingall and Susan McCarthy. (Though, sorry, it doesn't come out until January; but you can pre-order it.)

Marjorie is a longtime Friend of the Horn Book and article contributor, and co-author, with McCarthy, of the SorryWatch blog on which this book is based. In eleven highly entertaining and enlightening chapters, the book explores the whos, whats, whens, whys, and — most importantly — hows of good apologies. Chapter 2 spells out "Six Simple Steps to Getting It Right," and subsequent chapters include many real-life, case-study examples of celebrities, governments, politicians, corporations, and more, along with possible exceptions to the rules. 

Chapter 5, "'I'm Sorry I Chased You with a Booger': Teaching Children to Apologize," might be of special interest to readers of this blog. Although it's characteristically funny, it's also accessible and even (sometimes, maybe, on some days) actionable. Give it a try on Yom Kippur and let us know how it goes.
