I was out walking with my then 4-year-old daughter. She picked up something off the ground and started to put it in her mouth. I asked her not to do that. Why?Because its been lying outside and it is dirty and probably has germs. At this point, she looked at me with total admiration and asked, Wow! How do you know all this stuff?Uh, I was thinking quickly, …all moms knows this stuff. Um, its on The Mommy Test. You have to know it, or they dont let you be a Mommy.We walked along in silence for 2 or 3 minutes, but she was evidently pondering this new information. OH…I get it! she beamed, So if you flunk, you have to be the Daddy.
