Brooklyn's fascination with the number 16...

It all started last Christmas, we were opening presents up on Christmas day. Brooklyn was opening a Christmas card from Rich's grandparents. While she was opening it up, she says, "I hope it's 16 dollars!". It was a pretty random thing to say, we thought it was pretty cute. Then in March she started to get birthday cards from relatives, I would give her the birthday cards and she said the same thing... I hope it's 16 dollars!! Rich would always tease her and say, would you rather have a million dollars or 16 dollars? She would always say: 16 dollars! Rich had a birthday last April, she did the same thing. She would say, "Dad I hope you get 16 dollars for your birthday!" The other day I was in the car with the kids, I asked Brooklyn to practice counting to 20 for me. She said, "I want to count to 16. Then when we were on the way home from from temple square last week, she kept asking me when she could get married. I kept telling her when she got older and when she grew tall like me. She said, "Ok, I'll get married when I'm 16!". I dont think so!! The past few days, she keeps telling me she's getting married at 16. Should I be worried??
