My hair is black

Lizzy: My hair is black.
(2 weeks ago in preschool they learned the color black.)
Me: No it's not, Lizzy. It's brown.

Lizzy: Daddy, Mommy, my heart is broken!
(Referring to her crumbled Little Debbie Snack.)

Me: Lizzy, are you poopy?
Lizzy: Yes. I'm a poopy girl.

Lizzy: My hair is black.

Lizzy: It's my birthday.
Brother Nordhoff: Really? Is it today?
Lizzy: Yes.
(Her birthday is in September.)

***
Lizzy: Matthew is good.
(On the way to church. No prompting.)
Lizzy: Matthew's hair is black.
(It's bright red, actually.)
