Twisted Fates

I live by two principles: A. I never lie to humans. B. I never believe anything humans say-including myself. "Sir, I'd like to point out that your second point contradicts your first." "How so?" "If you never lie, then why don't you believe what you say?" "Oh, sorry, I forgot to mention-I never considered myself human." "?" Let me introduce myself. My name is Sincere-Sincere, who never lies. What? You've never heard of me? That's fine. It just means I haven't fooled you yet. But don't worry-you'll remember me soon enough.
