Our 18-month old Zoe can do lot’s of things. She goes up and down steps. She eats with a spoon. She lies. Wouldn’t you think fibbing was a more advanced skill, lower in the brain’s priority list of things it needs to develop? She can’t tie her own shoes, yet she avoids eye contact and responds with a “no, no” when we detect a fresh load in her pants and ask if she needs a diaper change. And they say we came from monkeys.
