There is a world of difference between
I didn’t do anything wrong
(therefore any problem that exists is your fault, because I am perfect, how dare you suggest that I am not perfect, you are wrong)
and
I didn’t mean to do anything wrong
(but I’m human, I made a mistake, I was rude and disrespectful, I didn’t listen to what you were asking for, I’m sorry, and I hope you can forgive me)
