Dimitra Triantafyllidou. In a good way. Because she often calls me to account, and not infrequently corrects me. I don’t enjoy it, but I do appreciate it.
BNRB (Grrr) compels me not to name the bad nemesis (in the literal sense). Suffice to say, he’s a guy with what I consider an unhealthy obsession with treating questions about the Roman Empire as questions about the Byzantine Empire. (Yes, they are contiguous, but we know what time period anyone but an ideologue means when they ask Roman Empire questions, and it isn’t the 15th century.) He’s blocked me, I’ve muted him (because I regard blocking as unmannered), and I mostly stay out of his foul-mouthed way.
