As I said before, someone secure in themselves has no need to defend against attacks. So if believing that is what you need to dismiss my observations of you, which deep down you probably know to have more truth to them then you'd like, then I have no desire to fight you on it.
So, believe whatever you wish. I had no delusions that I would convince you of anything. I have however found riling you up very amusing.
But as a caring person I'll leave you with this. You don't need to prove yourself to anyone, you don't need to lie or deceive. Trust me, just being you and not caring what people think is far more liberating. I don't pretend to be perfect at it, you have to work at it. But it's worth it.
Your education doesn't matter, your social skills and talent don't matter. Those are not the worthwhile tests of a worthwhile person. And on that most important quality you have far yet to go. I'm not there yet either, but trying is the point, not succeeding. Consider it.
