  I was walking outside with my then four 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? " she queried inexplicably. "Because it's been laying outside and is dirty and probably has germs. " At this point, she looked at me with total admiration and asked, "Wow!! How do you know all of this stuff?
" "Uh..." I was thinking quickly. Everyone knows this stuff. "Um, it's on the Mommy Test. You have to know it or they don't let you be a Mommy. " "Oh. " We walked along in silence for two or three minutes more, but she was evidently pondering this new information. "I get it!!! " she beamed. "If you flunk, you have to be a Daddy!
