When my DGD was about 3 or 4, she walked up to my Mom, put her little hands on each side of Mom's face and said, "You know how I know that you are old Gramma?" Mom said, "No Amber how do you know?" And she said, "because you've got all those cracks in your face." Everyone in the room cracked up, including my Mom. Talk about out of the mouths of babes!
