We had a wonderful weekend. Full of wonder. Literally. Went to the pub on the beach, and the grandchildren found "treasures", and each was examined with appropriate awe. You do actually have to wonder about some of the stuff that the sea washes up.

What I wonder about now is these silly mothers who insist on talking about their daughters as their best friends. It's usually just one daughter, and I always think, "What a burden for the girl!" I have three sons and only one daughter, and I don't want to be her best friend. I want to be her mother: her first point of call with a problem, yes, but not a buddy.

Some of these mothers actually go clubbing and pubbing with their daughters. Yuk. My daughter was at the beach with me yesterday, with her two gorgeous girls, and I was "Nan" for the afternoon - not Bridie, or best buddy - her children's grandmother, and her mother.

I can be anyone I want to be because we all have camouflage and we are all chameleons, but I want to be my daughter's mother and her children's grandmother. Her best friend, whoever she may be, is in place for different reasons.

I think that the sorriest sight of all is a woman over 40 wearing a denim jacket. She's usually her daughter's "best friend".
