I was out walking with my 5-year-old daughter. She picked up something off the ground and started to put it into her mouth.
I took the thing away from her and asked her not to do that.
“Why?” she asked.
“Because it’s been on the ground, and you don’t know where it’s been. It’s dirty. And it probably has germs.”
At this point, my daughter looked at me with absolute admiration and asked, “Mom, how do you know all this stuff? You are so smart.”
I thought quickly and replied, “All moms know this stuff. It’s on the Mom Test. You have to know it, or they don’t let you be a Mom.”
We walked along in silence for two or three minutes, but she was evidently pondering this new information.
“Oh, I get it!” she beamed, “So if you don’t pass the test, you have to be the dad.”
“Exactly,” I said.
