Here is a letter to the Columnist:
"I applaud your response to "Regretful," the gentleman who has been divorced from his first wife of many years and wants to apologize. I wholeheartedly agree with your encouragement regarding this apology. When my first husband and I had been divorced for 34 years, he called out of the blue and apologized for everything. I didn't realize I needed that, but I did. He died unexpectedly six weeks later. I'm thankful that he passed with a clear heart."
A perfect example of reaching out and taking care of regrets. In this way, the gentleman died a "good death, one with a clear heart".
