I was out walking with my grandson. He picked up something off of the ground and started to put it in his mouth. I took the item away from him and I asked him not to do that. "Why?" my grandson asked. "Because it's been on the ground; you don't know where it's been, it's dirty, and probably has germs. Sometimes germs make little boys sick and not feel good" I replied. At this point, my grandson looked at me with total admiration and asked, "Grandma, how do you know all this stuff? You are so smart." I was thinking quickly and said to him, "All Grandmas know stuff. It's on the Grandma Test. You have to know it, or they don't let you be a Grandma." We walked along in silence for 2 or 3 minutes, but he was evidently pondering this new information. "Oh...I get it! He beamed, so if you don't pass the test you have to be the Grandpa." "Exactly," I replied with a big smile on my face.
