The book presents five methods to express an apology. Your job is to identify the preferred method of your spouse/significant other, family members, co-workers, etc., then use their primary method when offering an apology. I'm sure the authors' idea in writing this book was to build on their "Five Languages" series of books, which is a clever idea; however, in my opinion, a better idea would have been to title the book "The Art of Apologizing" or perhaps "The Five Steps to a Sincere Apology" and teach readers to use all 5 methods in all apologies. One example in the book tells of a man who was annoyed by his girlfriend's continual complaining and negativity. When he confronted her, he was blown away by her response. She used all 5 languages and he knew, without a doubt, it was a sincere apology. They have had the best relationship ever since and plan to get married. Had the girlfriend narrowed her apology to one or two languages, the boyfriend probably wouldn't have been blown away, and their relationship may not have turned out nearly as well. I say, why limit an apology to anything less than all 5 languages. Give the one you offended a full, complete, and sincere apology and let the healing begin.
