As in previous years, it was immediate family + daughter's boyfriend + son + his girlfriend + his gang of friends, many of whom have been close since early high school. Party of 14, total.
My husband and I take all of them out to a medium-priced restaurant each year. It's lots of fun for everybody, a free meal for the college students, and probably the most accurate snapshot we get all year of what's going on in his immediate circle.
After we were seated, the waitress looked over the assembly -- a group whose parents or more distant ancestors hail from Africa, all over Asia (including Iran, Afghanistan, Japan and China), the Mediterranean, and pretty much everywhere in Europe -- and said, "What kind of group is this? It's obviously not a family."
Given that this is the gang that has been with my son all through his diagnosis and treatment for cancer, the gang who stuck with him and supported him and gave him a place to go where he could feel normal, I found myself thinking, "I don't know. I think it all depends on your definition."
