Dd7 asked me this morning
"Mom, did I ever have polka dots?"
"Polka Dots?"
"Yeah, polka dots"
"Polka dots on what? Shirts? Pants?"
"No, Mom! On my body? A boy in my class has polka dots on his face and body. Did I ever have them?"
"Ohhhhhhhhhh, Chicken Pox???"
"Yeah, that's what I meant, but they look like polka dots."
