I've often regretting giving an apology. Why should I have to apologize? They are the ones who thought I said something wrong. Typically, I do not put emotions in what I say. It is perfectly easy and simple to do. Yet, people believe that I believe what I mean and there are no exceptions. Or I am talking about something about them that I want them to change or dislike about them. But people are quite emotional and easily irritated.
I believe that if you are demanding an apology from someone, you might not deserve the apology.
