Help me Mall Santa!

So, Grace is very calm about Christmas this year. Grace knows that Santa is going to get her what she wants, and it is very big. Grace doesn’t need to tell Mommy or Daddy what it is she wants, because she already told Santa. Grace doesn’t need to write a letter to Santa because, well, she already told him when she was at the mall with her Grandmother, so why would she need to tell him again? Best part? Santa PROMISED that the big gift would be under the tree. Also, there’s a new rule, you can’t tell anybody what you ask Santa for, because then you might not get it (“it’s just like making a wish Mommy!) So. Do I go back to the mall, describe my little girl to him (“you MUST remember, she sat on your lap, she 4 years old, light brown hair, cut into a bob, pink Barbie boot, you must remember! How many girls look like that? What did she ask for dammit!!!)
I have a feeling there may be some s’plaining to do on Christmas day……
