Our nationality is part of who we are. It might not play a central part in our everyday life as far as customs may go, but there is something to be said for our heritage. Where we come from sometimes helps us know where we are going. Being American is a distinct nationality, but most Americans have different heritages. I enjoy American holidays and traditions, but it is also nice to have some elements of our other cultures as well.
For myself, I am Polish, Irish, and German. To be honest, I don't play up the nationalities all that much, but I think it's neat to know what you are. I would love to travel to those countries and experience what the culture would be like. The food, architecture, and people would all be so interesting.
One tradition that I have kept is a Polish one. Every Christmas we get special wafers decorated with religious scenes. Each member of the family breaks off a piece of their individual wafer and wishes the other a Merry Christmas and a Happy New Year. It is a warm memory I have of all the Christmas Eve's growing up. (And I do have to say that Polish Chrusciki sugar pastries are absolutely delicious).
Heritage to me is a little piece of our past that makes the unique story of our life a little more fascinating!
