family?

I was talking with him on the phone about housemate interactions - internal good will and the use of chorewars, billmonk and the like - when he made a distinction between a household where it was more like a family and ..(here I waited, because I couldn't tell what the contrast would be) .. shared housing like a dorm where people are more just sharing the space.

From reflecting on his distinction (his words held a mirror to my assumptions), I don't think I have ever considered living with people without considering them family. Certainly I have lived in some families composed of very autonomous individuals, or families of individuals with whom I did not interact all that much, but to live in a place with other people and not consider them some kind of family feels very foreign to me.

It now occurs to me that it is possible for others to live with people (including me) and perhaps not consider themselves to be in some kind of family. Especially, because I'm now guessing that sometime in the future, I will have to live with people that do not consider me family or whom I will not be able to consider as family. At least now, if this unfortunate event transpires, I will probably be confused for less time.
