"Don't mind my mom, she's 30!"

I drive up to a three car accident at an intersection. One of the drivers involved was a suburban mother with her kids with her. Off the bat her oldest daughter, probably about 8 or 9 years old is hopping around. She's asking "is someone going to jail?" "We were scared!" and "Wow!" Well, I asked for her driver's license and she had to return to the car to get it. The little girl then says "don't mind my mom, she's 30!" I could only shake my head. I'm 33, what would that child think of me?
