If you just found out your pregnant, but haven’t told your parents/new grandparents yet that they are now going to have a new grandchild. I would recommend doing it this way this Christmas. I’m sure it will be one of their greatest Christmas presents ever.
This happened a few Christmases ago in Baton Rouge, Louisiana. The poor guy finding out he is going to be a Grandpa for this first time just can’t keep it together. Absolutely adorable!
