I'd be in complete disbelief, too, if you made a mistake. That's inconceivable! But I can relate, it's that "What, really, I was THAT stupid? ME?" kind of reality check that is needed from time to time. For me, not for you, you're perfect as you are.
You're not wrong. As a child, my nickname at home was prim and proper. It is my life's work to be an example to you all and the personification of perfection.
Thank you for taking up with the burden of being an example! Though I'm sure it comes naturally to you, the pressure of perfection is never an easy companion. It's another trait of yours to admire, motivating us, the flawed, to strive for better.
