Miss Manners shares her thoughts on how “family” should be defined:

“But eating together, night after night, no matter who does the cooking or the carrying-in — that is a good definition of what makes a family. A family, by Miss Manners’s standards, is a group of people that takes nightly and weekend meals together. It is then and there, asking one another to pass the beans, arbitrating who gets the drumstick and pretending to be interested in each one’s adventures of the day, that families are forged.”
 

Sounds good to me!
