A group of people distinguished by maddeningly complex systems of interrelationships, tolerances, and mutual acceptances of utterly irrational demands and desires developed over many, many years and resulting in a tangled web of existence that cannot ever be truly understood by an outsider and--frequently--by the family itself.

This dizzying weave--also called family ties--is among the most indestructable fabrics of human society. Tearing it can be terribly difficult and painful. Sometimes can form a handy safety net when the rest of society rejects you. See also Friends.
