Dear Nana and Popo,
We are very sorry you will not be with us this holiday season.
Due to this very sad fact we have sent you a Christmas package but amidst the hustle and bustle we totally forgot to write on the outside DO NOT TO OPEN until Christmas day.
So...
DO NOT OPEN it until Christmas day.
By the way - in a week or so you'll be getting a package from us in the mail...Do NOT OPEN it until Christmas day.
I think I've made myself clear.
You will be sorely missed.
Love,
Three Little Bugs and Staff
P.S. Popo – we have updated your name in our records.
