I would say it's as odd as narcissism is, meaning: not that odd, infrequent, or unusual.
What it should have taught you is you don't express yourself clearly except in your own mind. I know everything about you. Your love for yourself and being right will not allow you ts accept any possibilities outside your own mind. It's your weakness. you're a quarter (if that) as good as you think you are, and as dumb as a stump. You're not crazy... You're stupid. But you are fun to play with.
