Grumpy old women is entertainment at its best... It involves literally women who have come of age and are going through identity crisis! these women moan and groan about various things ranging from how they have become their mothers, to 'empty nest syndrome' - when their children go off to university or leave home. They express themselves 'colourfully' and not too seriously (well thats the idea). I am not a grumpy old woman - yet, but I can feel their pain!
The world must really be scary when you realize you have become the person your parents warned you about!
