commonness

    Every social group has a code. For larger ones, they are called laws. In the smaller, there are looser but still firmly-held understandings of what can and what cannot be done for the unit to survive.
    In most groups of female friends - even groups of two - there is what has come to be known as a 'girl code.' The most basic of the rules in the girl code is this: don't take what I've already said that I want. It is not complicated. It is the moral equivalent of the Golden Rule. It is the adult correlate to "dibs."
    It does not seem too much to ask, really. But I suppose that if it is too much to ask, that defines the "relationship."
