One thing I love

So, Laur's at my place and we're putting a frozen pizza in the oven, then going to turn on a movie. Mom's oven has no timer. Worried that we'll burn the place down, or at least be eating char for dinner, Laur asks how we'll remember that something's in the oven.
"I'll get Phil to let us know," I say, distracted with the putting of the pizza on the hot rack.
Laur is slient for a moment, then,
"How will a plant let us know when our pizza is ready?"

So, what do I love?
I love that my best friend not only knows that I have names for both my plant and the microwave, but that she knows which one is which.
