Hubby on your lizard brain

Hubby talking to Frankie:

Your brain has three parts. The bottom part is your lizard brain; the next part is your animal brain; and the very top part is your human brain. [Frankie starts to giggle.] When you get angry you are using your lizard brain, and lizards are not good at making decisions. They can only decide to do one of two things: run or attack. [Frankie is laughing and checking with me to see if Hubby is at all serious.] So before you decide what to do you need to be calm so you can decide with your human brain. Trying to make decisions with your lizard brain is like using a military tank to thread a needle. [Lots of giggling.]

I will spare you the accounting of the events that made this story appropriate.
