This is good advice for an apology for any important relationship. I particularly liked the suggestion to be specific about what you are apologizing for. Not saying "for anything I've ever said or done". I received an "apology" worded this way recently. It was NOT a sincere apology and I did not believe it for one second! Nice try. They were just words. Very disrespectful (and stupid) of you to think I'd fall for it.
