My “tuna of the sea” moment

So I had my “tuna of the sea” moment…
Jamie: “How’s the pizza going?”
Me: “Fine… how do I know when it’s done?”
Jamie (opening oven): “Uh, you weren’t supposed to cook the breadsticks and the pizza at once…and they are on the wrong trays.”
Me: “What? Why?”
Jamie: “And what temperature are they supposed to be?”
Me: “It says 425 for a regular oven and 400 for a conventional oven…”
Jamie: “Conventional oven?”
Me: “Yeah, and your oven is old so I assumed it was a conventional oven…”
Jamie: “Convection oven. And my oven isn’t a convection oven.”
Me(rereading the instructions): “OH! It does say convection… what’s a convection oven?”
And yes, I looked up convection oven:
Convection ovens or fan ovens or turbo ovens augment a traditional oven by circulating heated air using a fan.
Hmmf. At least I learned something today!
