More clarity in language is important, but as we already know, communication isn’t just about exchanging information—the words we use also influence our emotions and relationships.
Have you ever noticed how some people are great at giving apologies? I was taught that it is a very important life skill to be able to apologize correctly. The first rule was to tell someone that I wanted to apologize about (insert my offense here). This was to be followed by an explanation of how I knew I was wrong. Finally, an apology was coming to a finish with an explanation of what I would do differently in the future and if needed, ask for forgiveness. If an apology was presented sincerely without any kind of excuses, it was a solid effort (whether accepted or not). Things to avoid were "I'm sorry but if you hadn't", or excusing your behavior by explaining it, such as "i was only trying to". A good apology got right to the point, didn't make excuses, recognized the offense, had a plan for fixing the behavior (mine, not theirs) and actually asking for forgiveness or understanding. That's it. That's the whole thing. Nothing more, nothing less.
