Mother of the "bride"

My daughter organised a festival of love for herself and her partner on the weekend past as a kind of avowal of love ceremony. Years ago we would have called this a wedding. It was great fun and really very moving for all who were there. I am surprised that this seems to be as much a rite of passage for the mother of the bride as for the bride herself. I am still in the liminal phase and feeling an odd sense of loss.
