They always say that as a parent you should NEVER play favorites or have a 'favorite' child. Some people do, but you should always try really really hard to not ever let them know it. Right?
So does this rule not apply to grandparents as well? This grandma has a 'leaderboard' in her house that has the numbers 1-10 with little magnets next to the numbers. Then she has a picture of each of her grandchildren attached to a magnet and she will place each child where she thinks they 'rank' depending on whether or not they are a huge disappointment I guess.
Watch what she does when her #4 favorite grandchild shows her his new tattoos.
