"You don't look like a mom"

The girls and I went to the mall yesterday. On the way, Lizzy informed us she packed a hairbrush in her purse, just in case anyone needed to brush their hair. A few seconds later, this was our conversation:

Lizzy: "Mom, you don't look like a mom."
Me: "Why?"
Lizzy: "My don't know. But you look like a Grandma. Maybe you brush your hair and that help."

I took the brush, pretended to brush my hair, and gave it back to Lizzy.

Lizzy: "There. That much better. Now you look like a Mom. Now Lexi, you need to brush your hair."
Lexi (who had her hair in a ponytail): "I'm ok."
Lizzy: "Fine. You look like a frog though."
