Families are not communistic. I think of them as a unit (as most economists do). The family unit is the basic grouping of societies and operate along much the same lines as tribes and other small groups.

People do say (wrongly) that families are communistic.

Commies don't embrace these definitions anymore, but they did make them and I think they're perfectly fine distinctions to make. They just don't like having been on the wrong side of history (another one of their lines).

What "Capitalism" Really Means

As everyone should be!! However the communists do not embrace any kind of definition like this. 
My wife once told me about sisters: What’s hers is mine, what’s mine is mine.
To me this sounded just like a good communist, but only intrafamilial.
