I was out walking with my 4 year old daughter.

She picked up something off the ground and started to put it in her mouth. I took the item away from her and I asked her not to do that.

'Why?' my daughter asked. 'Because it's been on the ground, you don't know where it's been, it's dirty, and probably has germs' I replied.

At this point, my daughter looked at me with total admiration and asked, 'Momma, how do you know all this stuff, you are so smart.'

I was thinking quickly. '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 2 or 3 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 replied back with a big smile on my face.
