Goosey Loosey

This evening after we finished eating supper Paige and Emma went outside to play with their friends. After a minute Emma came back in, started to open the closet door and pull out a jacket while declaring that she had "chicken pox".
"What!?" I said.
"I have the chicken pox." Emma responded.
I asked incredulously, "How can you have chicken pox!? If you had chicken pox your body would be covered in red, itchy bumps!"
"Well, I don't know what they're called!" Emma said.
I then replied, "I have no idea what you're talking about." I was busy cleaning the kitchen at this time so I was a bit distracted.
Emma then told me, "I'm cold, and I need a jacket, and I have...something about a chicken..."
As I was loading the dishwasher I thought on that for a few seconds, and then I burst out laughing. "You mean you have the goose bumps?"
"Yeah!!" Emma said.
Case closed. ☺
