I've taught the twins the location of New Zealand on the globe in their living room.
Now Thiel will say, "I found New Zealand! See, Missi?"
And Abby will say, "You going to New Zealand, Missi?"
I reply with, "Wow" and "Yes," respectively.

They start daycare in two weeks and I will be out of a job (but it's a way bigger deal than just that).
