I saw that interview this morning with this girl. It was really quite amazing. She had exceptional poise and confidence in front of the camera. There are teenagers (and adults, I’m sorry to say) that don’t have her vocabulary and command of the language. For a six year old, it’s really something.
A very remarkable little lady. She’s going to be somebody important some day.
That's what happens when you don't talk baby talk to your kids. Just talk to them as if they were adults and stretch them, and they will learn.
