Wifey B: We have those in our family that we'd drop anything to do something for them like this. I applaud Menzies.
Now, as to family definition. there is no concrete definition of "immediate family" and some definitions do include aunts, uncles and cousins. Immediate family is only defined in specific laws in some states or countries, such as inheritance law, and specific policies such as bereavement or insurance.
Now, we really stretch these definitions. We claim as our mother and father, and yes as husband and wife we claim the same ones, people to whom we have no blood relationship. In fact, we're not related by blood to any of our family. We have a "daughter" we didn't meet until her high school graduation.
It gets "worse" as you might see it. Our niece, Aurora, the daughter of the daughter of the couple we claim as our parents, has redefined it all beautifully. There's a girl her age in South Florida she first met when they were three and this girl is firmly and without question her "cousin." Furthermore all the people she's met at our house, all the girls from 18 to 30 are "cousins." She actually had a little debate with her kindergarten teacher and she clearly had heard this from her mom as she said "I refuse to be limited by conventional rules."
Point is, if Menzies calls someone immediate family, then they are that to him, and unless we're in some legal discussion, he can determine who he considers immediate. I praise that there are people in his life he'll put above cruising.
