You clearly did not read my last post. Or failed to comprehend it. So let me take this step-by-step:

(1) Sometimes, people say things that they mean, but do it in an inappropriate setting (remember, this was my funeral example);

(2) Sometimes, people say things that they mean, but do it in an unnecessarily mean/aggressive way (remember this example, too?);

(3) You stated that OP shouldn't apologize if she meant what she said.

(4) I responded by saying that wasn't necessarily true. For example, see (1) and (2). Saying what you meant to say isn't the end of the reasoning here (although it's a pretty clear full stop for you). If you say what you mean in an inappropriate setting or in a cruel way, then you have something to apologize for.

(5) For example, and again referencing (1) and (2), if either of those happened I would fully expect an apology. "I'm sorry I brought this dishes thing up at your dad's funeral, that was thoughtless of me." Or "I'm sorry I screamed at you about the dishes instead of talking to you about it calmly."

(6) Now, this is the part you're struggling with so pay attention: I never said that people should apologize for saying what they meant. I'm saying that even if someone does say exactly what they mean, they may still owe the other person an apology for something other than saying what they mean.. Again, please reference (1) and (2). (5) as well.

(7) OP said she wants to apologize. You stated she didn't have anything to apologize for. But the truth is that you don't actually know that, do you?;

(8) The reason you don't know is because OP didn't specifically state why she wanted to apologize.

(9) If OP wanted to apologize like my example in (5), that would be a very adult, mature, and reasonable thing to do. And she should.

That's all I got. I literally have no idea how else to explain this. If you still don't get it, well good luck mate.
