My father was one of seven kids from Kansas. During the Great Depression, he got married and the next day took the freights West. There he eventually joined the Coast Guard and at the end of WW II ended up in Newport Beach. He did well in real estate and luckier yet, did not lose it back during one of the many down cycles.
He and Mom lived full and good lives, and their kids, we four plus one foster brother, still are going strong. Our foster brother, Gary, came from a broken family and joined us at the age of 16.
At Christmas, I no longer am sure who my whole family is. Yes, I know it includes my brothers and sisters and their offspring and their offspring too. But it is more than that. My former wife lives near me in Laguna and our children navigate between us in a manner that works for all concerned. During holidays it can be tricky, but we all accommodate one another and go to the same music recitals together.
