We were discussing people Gary saw at the funeral, and he described someone as his cousin's daughter.
"So," I said, "Your first cousin once removed."
"Don't use that term. That's a silly term."
"Well, it's the right term. What would you call her?"
He thought a moment. "She's my CousinNiece."
"So what's her daughter," I asked, trying to show him the value of "twice removed."
"My great CousinNiece. Duh."
