Tech Support for Schrodinger's Oven

My cell phone rings

Me: Hello, IT Support, this is Lee.
Habtamu: Hi Dad.
Me: Oh... Hi what's up?
H: I was calling to find out when you were coming home.
Me: 5 o'clock.
H: Ok. Do you know if the lasagna's done?
Me: What?
H: Is the lasagna done.
Me: I don't know. You're the one who is at home.
H: But I'm not in the kitchen and I can't tell if it's done.
Me: Ok, well is it in the oven?
H: I don't know.
Me: Well how am I supp...
H: YORDANOS! DAD WANTS TO KNOW IF THE LASAGNA IS IN THE OVEN!
Me: You know you could jus...
H: YORDANOS!
Me: sigh... (I happen to know the phone cord stretches to the kitchen)
H: DAD NEEDS TO KNOW IF THE LASAGNA IS IN THE OVEN!
(Muffled argument ensues)
H: No.
Me: No, what? It's not in the oven?
H: Yordanos says it is not in the oven.
Me: Did it used to be in the oven?
H: Yes. Mom told me to put it in and I did. We took it out to see if it was done, but we can't tell.
Me: Was the oven on?
H: Yes. I turned the oven on.
Me: What temperature is the oven set at?
H: I don't know, I'm not in the kitchen. YORDAN...
Me: Wait! How long has the lasagna been in the oven?
H: I don't know... like... maybe... 20 minutes?
Me: What time did you put it in? (Do you see what I did there?)
H: Like, 20 minutes ago dad. (Do you see how it didn't matter?)
Me: Ok, Ok... Um, is it hot?
H: What?
Me: Is. The. Lasagna. Hot?
H: YORDANOS! DAD WANTS TO KNO... (phone gets muffled)
H: She says it's boiling. Look, dad. I just want to know if dinner is ready.
Me: Sure.
H: When are you coming home?
Me: 10 minutes. Don't eat until I get there.
H: Ok. Bye. I love you.
Me: Love you too.

I get home and the "reheated" lasagna leftovers, which haven't even reached room temperature yet, are sitting on the oven. The oven is still running at 350 degrees. Neither child is in the kitchen. 3 minutes in the microwave and dinner is served.

Footnote: Erwin Schrodinger is famous for trying to figure out whether a (theoretical) cat in a box would be dead or alive without actually opening the box. Kind of like me trying to find out whether or not dinner was cooked without actually having any useful prior information.
