After I told Deuce he didn't have to hand wash the 7 (!!!) travel mugs The Pit Boss brought home from the office if they didn't all fit in the dishwasher.
Me: Truvia. It's Truvia, not Alluvia.
Bear: Then what's alluvia?
Deuce: Some random word you just made up.
TPB: Well, alluvial plain.
Me: That's not alluvia. Alluvia isn't a word.
TPB whips out his phone, types, and reads aloud: Alluvia is the plural of alluvium.
Bear: Right, and Dad would never just use one alluvium in his coffee.
