Just Rest Your Mouths

I really have to pay closer attention to our kids. Kids say whatever is on their little minds. When they are exposed to something they aren't cognizant of, they have to say something. Kids are curious and I respect that. I just have to pay closer attention to body language.
Yesterday, on our way to the car from school, I ran into a parent who is Muslim. Maurissa and I were already familiar with this mom and her children. One of her daughters was in the same class with Maurissa last year. So the way they were dressed (as Muslims) was no shock for Maurissa. Well this was all new for our son, Myles.
She (the parent) and I said our goodbyes and headed for our cars. Four steps later, Myles says,
"Mama, why is she wearin' that big bonnet?"
For a second I couldn't move. Too shocked... embarrassed... wishing I could grab the words out of the air and put them back in his mouth.
I just pulled him along. "Come on here and just be quiet!"
I was hoping she did not hear him.
A couple of steps more and his sister chimed in.
"She wears that over her head because her hair is messed up... Duh! You don't know nothing!" she tells him.
"Just get in the car y'all," I said with my teeth clinched.
Too late. They were enveloped in their own conversation.
"They make those bonnets in Africa," Myles said.
"Yep! You know Myles you might be right," she said.
"Mama, they live in Africa," Myles added.
"JUST GET IN THE CAR!" I shouted.
"Uh-oh, she mad at you," Maurissa whispered.
"Naw, she talkin' to you," Myles whispered back.
"Just rest your mouths," I said slowly. "Just rest your mouths."
I looked in my mirror. They were sitting there with their hands over their mouths snickering.
