To understand this, you must understand the nature of the bride. The light-hared, from whcih brdies are, were once as intelligent as we. Over the years, they have let their beauty go to their heads, trading on it to have an easy life. This has led to a decline in their intelligence. Now, while they can cleverly use a wand, in terms of the larger matters, they are not much more intelligent than a bright cat. Like all semi-intelligent persons they resent and fiercely resist the controlling hand that is needed to guide, prod and even force them to proper behavior.
We are a proud people. Unfortunately, this is true of pretty much all of us. While some of us ought to be filled with pride, for many this is an impedement to fullfilling their proper role in life
Nowhere is this more true that for a bride. Her proper place is under the control of her housemistress. Her proper role is that of a lesser being. part body servant, part child and part doll. Her proper behavior is one of unquestioned obedience. The only way we know that shi has been trained correctly and is broken of any pride is for her to show the proper feelings; those of the lesser person; fear, sadness and abject humility.
These are not traits born into a Fairy. She has to be made to accept them. This is a process begun at an early age, culminating in the tears, screams and sobs as she is laid on the rubber-covered Bridal Cot with her humiliatingly short rubber Bridal Dress skirt being lifted to show the glint of the rubber panties over a thick diaper as the new Housemistress prepares to see if her future is to be smooth or troubled and it should be an enjoyable one for those into whose family she will be brided.
To "cry like a bride" and "wet like a bride" have become a part of our language meaning to be brought helplessly to tears by sorrow or joy or anything that touches deeply and to have to use the restroom very badly and quite vigorously. When I recieved my rank as Rubber Lady, I wrote in my diary, "...I was so filled of pride and gladness that I cried like a bride with joy. and Proctress Elandryl put her arm around me and with my head on her shoulder, my warm tears fell upon her dress and she said 'Lady Tiarandra. You have earned the right to those tears.'...". Just the last week I had drunk an abundance of sandrahl with it's usual aftermath and told the others that I will soon "wet like a bride". in neither case was I ill at ease or being chastized. The sandrahl and the party were joyful events and what person is not absolutely thrilled with getting her Charter. So, though these phrases point to a, hopefully, unhappy occasion, they are watchwords amongst our people.
