"Mama," my nine-year-old son said. "Do you know how to tell if you have a virus?"
I nodded. "Usually you feel sick - you have a sore throat, a runny nose, headache and maybe a tummy ache.
Bubba shook his head. "No, Mama. That's not how you tell."
I looked at that kid. "Okay, Bubba. How do you tell?"
He lay down on the ground, face up. "You lay down just like this. Then you put both of your hands over your belly. Then somebody has to press down on them. If you laugh, you're fine. If you don't laugh, you have a virus. So Mama, press down on my hands, and I'll show you how it works."
I shook my head and pressed down on his hands.
He giggled. "See, Mama? No virus!"
(So ladies and gentlemen, if you ever think you might have a virus, do this simple test. Then you'll know for sure!)
