Because Three. (A short skit copied from a real today):

Loki: Mommy! Can you get that piece of my thing?
Me: What thing?
Loki: My thing!
Me: Which thing?
Loki: THE THING!
Me: No. I can’t. Because I don’t know which thing.
Loki: Yes you do!
Me: I am sorry, that does not work.
Loki: YES IT DOES!
Me: No. Really. It doesn’t.
Loki: Okay, I will get the thing.
Me: Okay.
Loki: WHERE IS MY THING?

Today needs more coffee.
