Maybe those of us in the US just have a more fuzzy idea about what constitutes our own individual cultural heritage. In my case, my heritage is Scottish, Irish, English, French, German, Canadian, and Bermudan. In my son's case his heritage is all of those plus possibly some Jewish.

I wasn't raised with an awareness of the specific cultural artifacts of all of those nations. I got a pretty good dose of "American" culture, which, quite frankly doesn't particularly interest me. My son got some of his cultural influences from the things I got when I was growing up, and we chose some others that were new to both of us.
