Spending the Christmas holidays in two different countries not only implies the use of two different languages, but adapting to two different cultures. To an adult this can prove challenging, especially if you are not used to different traditions and customs during the Christmas season, but to a child who grew up this way, nothing is strange… not even having two days with presents and two Christmas trees.
My boys have spent every Christmas with some time spent in England (before Christmas) and then Christmas day and the rest of the holiday in Italy. Despite being British, they never had turkey and roast potatoes; they are accustomed to lasagne and Italian antipasti instead.
I think sometimes they are confused between Santa and Babbo Natale. Is he one fat person in a red suit or two different ones? As long as he keeps on bringing presents, I don’t think they will mind though.
What I found most unusual is that every year the boys open their English presents on the 23rd and their Italian presents on the 25th. As a consequence, they think it’s normal to spend Christmas Eve at the airport!
